Features

The TMCM-1160 is a single axis controller/driver module for 2-phase bipolar stepper motors with state of the art feature set. It is highly integrated, offers a convenient handling and can be used in many decentralized applications. The module can be mounted on the back of NEMA 23 (57mm flange size) or NEMA 24 (60mm flange size) stepper motors and has been designed for coil currents up to 2.8 A RMS and 12, 24 or 48 V DC supply voltage. With its high energy efficiency from TRINAMIC’s coolStep™ technology cost for power consumption is kept down. The TMCL™ firmware allows for both, standalone operation and direct mode.

TRINAMICS UNIQUE FEATURES – EASY TO USE WITH TMCL

stallGuard2™
stallGuard2 is a high-precision sensorless load measurement using the back EMF on the coils. It can be used for stall detection as well as other uses at loads below those which stall the motor. The stallGuard2 measurement value changes linearly over a wide range of load, velocity, and current settings. At maximum motor load, the value goes to zero or near to zero. This is the most energy-efficient point of operation for the motor.

Figure 1.1 stallGuard2 load measurement SG as a function of load

coolStep™
coolStep is a load-adaptive automatic current scaling based on the load measurement via stallGuard2 adapting the required current to the load. Energy consumption can be reduced by as much as 75%. coolStep allows substantial energy savings, especially for motors which see varying loads or operate at a high duty cycle. Because a stepper motor application needs to work with a torque reserve of 30% to 50%, even a constant-load application allows significant energy savings because coolStep automatically enables torque reserve when required. Reducing power consumption keeps the system cooler, increases motor life, and allows reducing cost.

Mechanical and Electrical Interfacing

Dimensions and Mounting Holes

• The dimensions of the TMCM-1160 controller/driver board are approx. 60 mm x 60 mm in order to fit on the back side of the 60 mm stepper motor.
• Maximum component height above PCB level without mating connectors is around 10.5 mm (jumpers for RS485 / CAN termination included).
• Maximum component height below PCB level is around 4 mm.
• There are four mounting holes for M3 screws for mounting the board either to a NEMA23 (two mounting holes at opposite corners) or a NEMA24 (other two mounting holes at opposite corners) stepper motor.

Connectors of TMCM-1160
The TMCM-1160 offers seven connectors including the motor connector which is used for attaching the motor coils to the electronics. In addition to the power connector there are two connectors for serial communication (mini-USB connector and 5pin connector for RS485 and CAN) and three connectors for Step/Direction, multipurpose input/output signals, and for an external encoder.

The multipurpose connector offers two general purpose outputs, two general purpose inputs, two inputs for stop switches and one for an additional home switch.
The power supply connector offers separate inputs for driver and for logic power supply plus hardware shutdown input. Leaving the shutdown input open or tying it to ground will disable the motor driver stage in hardware. For operation, this input should be tied to supply voltage.

Power Connector
This module offers separate power supply inputs for digital logic (pin 2) and driver/power stage (pin 1). Both supply inputs use common ground connections (pin 4). This way, power supply for the driver stage may be switched off while still maintaining position and status information when keeping digital logic supply active. Due to internal diode the digital logic supply has to be equal or higher than the driver/power stage supply. Otherwise the diode between driver/power stage supply and digital logic supply might short the separate supplies.

+UDRIVER SUPPLY ONLY
In case power supply is provided only to the power section (pin 1) an internal diode will distribute power to the logic section. So, when separate power supplies are not required it is possible to just use pin 1 and 4 for powering the module. If so, pin 2 (logic supply) and pin 3 (/SHUTDOWN input) can be connected together in order to enable the driver stage.

ENABLING THE DRIVER STAGE
Connect /SHUTDOWN input to +UDriver or +ULogic in order to activate the driver stage. Leaving this input open or connecting it to ground will disable driver stage.
A 4-pin JST EH series B4B-EH connector is used as power connector on-board.

| Pin| Label| Description
---|---|---|---
| 1| +VDriver| Module + driver stage power supply input
2| +VLogic| (Optional) separate digital logic power supply input
| 3| SHUTDOWN| Shutdown input. Connect this input to +VDriver or +VLogic in order to activate driver stage. Leaving this input open or connecting it to ground
| | | will disable driver stage
| 4| GND| Module ground (power supply and signal ground)

Table 3.2 Connector for power supply

Power Supply
For proper operation care has to be taken with regard to the power supply concept and design. Due to space restrictions the TMCM-1160 includes about 20 µF / 100 V of supply filter capacitors. These are ceramic capacitors which have been selected for high reliability and long life time.

HINTS FOR POWER SUPPLY CABLES

• ­ Keep power supply cables as short as possible. ­
• Use large diameters for power supply cables.

CAUTION!

**| Add external power supply capacitors!**

It is recommended to connect an electrolytic capacitor of significant size (e.g. 2200 µF / 63 V) to the power supply lines next to the TMCM-1160 especially if the distance to the power supply is large (i.e. more than 2-3m)!
Rule of thumb for size of electrolytic capacitor:   c = 1000  × IMOT

A In addition to power stabilization (buffer) and filtering this added capacitor will also reduce any voltage spikes which might otherwise occur from a combination of high inductance power supply wires and the ceramic capacitors. In addition it will limit slew-rate of power supply voltage at the module. The low ESR of ceramic-only filter capacitors may cause stability problems with some switching power supplies.

---|---
**| Do not connect or disconnect motor during operation!
Motor cable and motor inductivity might lead to voltage spikes when the motor is disconnected / connected while energized. These voltage spikes might exceed voltage limits of the driver MOSFETs
**| and might permanently damage them. Therefore, always disconnect power supply before connecting / disconnecting the motor .
**| Keep the power supply voltage below the upper limit of 51V!
Otherwise the driver electronics will seriously be damaged! Especially, when the selected operating voltage is near the upper limit a regulated power supply is highly recommended. Please see also chapter Fehler! Verweisquelle konnte nicht gefunden werden.Fehler! Verweisquelle konnte nicht gefunden werden. (operating values) .
**| There is no reverse polarity protection!
The module will short any reversed supply voltage due to internal diodes of the driver transistors.

Serial Communication Connector
The module supports RS485 and CAN communication via this connector.

CAN interface will be de-activated in case USB is connected due to internal sharing of hardware resources.

A 2mm pitch 5-pin JST B5B-PH-K connector is used for serial communication.

| Pin| Label| Description
---|---|---|---
1| CAN_H| CAN bus signal (dominant high)
2| CAN_L| CAN bus signal (dominant low)
3| GND| Module ground (system and signal ground)
4| RS485+| RS485 bus signal (non inverted)
5| RS485-| RS485 bus signal (inverted)

Table 3.3 Connector for serial communication

RS485
For remote control and communication with a host system the TMCM-1160 provides a two wire RS485 bus interface. For proper operation the following items should be taken into account when setting up an RS485 network:

1. BUS STRUCTURE:
   The network topology should follow a bus structure as closely as possible. That is, the connection between each node and the bus itself should be as short as possible. Basically, it should be short compared to the length of the bus.
   Figure 6.4 Bus structure

2. BUS TERMINATION:
   Especially for longer busses and/or multiple nodes connected to the bus and/or high communication speeds, the bus should be properly terminated at both ends. The TMCM-1160 does offer on-board termination resistors which can be activated with the help of a jumper. The jumper has to be removed for units not connected to one end of the bus!

3. NUMBER OF NODES:
   The RS485 electrical interface standard (EIA-485) allows up to 32 nodes to be connected to a single bus. The bus transceiver used on the TMCM-1160 units (SN65HVD485ED) has 1/2 of the standard bus load and allows a maximum of 64 units to be connected to a single RS485 bus.

4. NO FLOATING BUS LINES:
   Avoid floating bus lines while neither the host/master nor one of the slaves along the bus line is transmitting data (all bus nodes switched to receive mode). Floating bus lines may lead to communication errors. In order to ensure valid signals on the bus it is recommended to use a resistor network connecting both bus lines to well defined logic levels. In contrast to the termination resistors this network is normally required just once per bus. Certain RS485 interface converters available for PCs already include these additional resistors (e.g. USB-2-485).
   
   CAN
   For remote control and communication with a host system the TMCM-1160 provides a CAN bus interface. Please note that the CAN interface is not available in case USB is connected. For proper operation the following items should be taken into account when setting up a CAN network:

5. BUS STRUCTURE:
   The network topology should follow a bus structure as closely as possible. That is, the connection between each node and the bus itself should be as short as possible. Basically, it should be short compared to the length of the bus.
   
   Figure 3.6 CAN bus structure

6. BUS TERMINATION:
   Especially for longer busses and/or multiple nodes connected to the bus and/or high communication speeds, the bus should be properly terminated at both ends. The TMCM-1160 does offer on-board termination resistors which can be activated with the help of a jumper (see chapter 7). The jumper has to be removed for units not connected to one end of the bus!

7. NUMBER OF NODES:
   The bus transceiver used on the TMCM-1160 units (TJA1050T or similar) supports at least 110 nodes under optimum conditions. Practically achievable number of nodes per CAN bus highly depends on bus length (longer bus -> less nodes) and communication speed (higher speed -> less nodes).

Multipurpose I/O Connector
A 2mm pitch 8-pin JST B8B-PH-K connector is used for connecting general purpose inputs, home and stop switches and outputs to the unit:

| Pin| Label| Description
---|---|---|---
1| OUT_0| General purpose output, open drain (max. 1A) Integrated freewheeling diode connected to +VLogic
2| OUT_1| General purpose output, open drain (max. 1A) Integrated freewheeling diode connected to +VLogic
3| IN_0| General purpose input (analog and digital), +24V compatible Resolution when used as analog input: 12bit (0..4095)
4| IN_1| General purpose input (analog and digital), +24V compatible Resolution when used as analog input: 12bit (0..4095)
5| STOP_L| Left stop switch input (digital input), +24V compatible, programmable

internal pull-up to +5V

6| STOP_R| Right stop switch input (digital input), +24V compatible, programmable internal pull-up to +5V
7| HOME| Home switch input (digital input), +24V compatible, programmable internal pull-up to +5V
8| GND| Module ground (system and signal ground)

Table 3.4 Multipurpose I/O connector

All inputs have resistor based voltage dividers with protection diodes. These resistors also ensure a valid GND level

For reference switch inputs (STOP_L, STOP_R, HOME) a 1k pull-up resistor to +5V can be activated (separately for each input). Then these inputs have a default (unconnected) logic level of “1” and an external switch to GND can be connected.

Digital Inputs STOP_L, STOP_R, and HOME
The eight pin connector of the TMCM-1160 provides three reference switch digital inputs STOP_L, STOP_R and HOME. All three inputs accept up to +24 V input signals. They are protected against these higher voltages using voltage resistor dividers together with limiting diodes against voltages below 0 V (GND) and above +3.3 V DC.

Figure 3.6 STOP_L, STOP_R and HOME inputs (simplified input circuit)

All three digital inputs are connected to the on-board processor and can be used as general purpose digital inputs!

General Purpose Inputs IN_0 and IN_1
The eight pin connector of the TMCM-1160 provides two general purpose inputs which may be used as either digital or analog inputs.

GENERAL PURPOSE INPUTS AS ANALOG INPUTS
As analog input they offer a full scale input range of 0… +10 V with a resolution of the internal analog-to-digital converter of the microcontroller of 12bit (0… 4095). The input is protected against higher voltages up to +24 V using voltage resistor dividers together with limiting diodes against voltages below 0 V (GND) and above +3.3 V DC.

Figure 3.7 General purpose inputs (simplified input circuit)

Outputs OUT_0, OUT_1
The eight pin connector of the TMCM-1160 offers two general purpose outputs OUT_0 and OUT_1. These two outputs are open-drain outputs and can sink up to 1 A each. The outputs of the N-channel MOSFET transistors are connected to freewheeling diodes each for protection against voltage spikes especially from inductive loads (relays etc.) above supply voltage.

• In case free-wheeling diodes are connected to VDD supply voltage: none of the two outputs should be connected to any voltage above supply voltage of the module.
• It is recommended to connect +Vlogic of the power connector to the power supply output in case the outputs OUT_0/1 are used to switch inductive loads (e.g. relays etc.).

Figure 3.8 General purpose outputs

Step/Direction Connector
A 2mm pitch 4-pin JST B4B-PH-K connector is used for step and direction input signals. This is an option in case the on-board controller is used for configuration of the driver stage, only. The Step/Direction input is optically isolated and will allow direct control of the driver stage.

Please do not attach any signal to this input if the on-board motion controller is used! Otherwise step or direction signal connected here might interfere with signals generated on-board.

1| COM| Common supply for the opto-coupler inputs (+5V… +24V)
2| ENABLE| Enable signal input (function depends on firmware)
STEP| Step signal input (connected to step input of TMC262 driver IC)
4| DIRECTIO| Direction signal (connected to direction input of TMC262 driver IC)

Table 3.4 Connector for step/direction signals

Step / Direction / Enable Inputs
The inputs Step, Direction and Enable are electrically (optically) isolated from the power supply and all other signals of the TMCM-1160 module. These inputs have one common reference input COMMON.
The COMMON input should be connected to a positive supply voltage between +5 V and +24 V. Step / Direction / Enable signals might be driven either by open- collector / open-drain outputs or by push-pull outputs.
In case of push-pull outputs the COMMON supply voltage should be equal / similar to the high signal voltage level of the push-pull drivers.

Figure 3.9 Step / Direction / Enable inputs

Encoder Connector
The module supports an external incremental a/b/n encoder via this connector. The external encoder may be used in addition or as an alternative to the internal / on-board sensOstep encoder.
A 2mm pitch 5-pin JST B5B-PH-K connector is used for connecting an external encoder with TTL (+5 V push-pull) or open-collector signals directly:

| Pin| Label| Description
---|---|---|---
1| GND| Module ground (system and signal ground)
2| +5V| +5V supply output for external encoder circuit (100 mA max.)

4| ENC_B| Encoder b channel input (internal pull-up)
5| ENC_N| Optional encoder n / index channel input (internal pull-up)

Table 3.5 Connector for an external incremental encoder

Encoder Inputs
The TMCM-1160 offers a dedicated encoder input for incremental a/b encoders with optional n / index-channel.
Encoders with +5 V push-pull (TTL) signals or open-collector signals (on-board pull-ups) might be connected directly. This connector offers a +5 V supply output for supply of the encoder circuit. Up to 100mA might be drawn from this output.
Connecting an external encoder is an option. An external encoder might be used in addition or as alternative to the internal sensOstep encoder.

Mini-USB Connector
A 5-pin standard mini-USB connector is available on board. This module supports USB 2.0 full-speed (12Mbit/s) connections.

Please note:

• On-board digital core logic (mainly processor and EEPROM) will be powered via USB in case no other supply is connected. The USB connection might be used to set parameters / download TMCL programs or perform firmware updates while power supply for the module (and the rest of the machine) has been switched off or is not connected.
• CAN interface will be de-activated as soon as USB is connected due to internal sharing of hardware resources.

Table 3.6 Mini USB connector
For remote control and communication with a host system the TMCM-1160 provides a USB 2.0 full-speed (12Mbit/s) interface (mini-USB connector). As soon as a USB-Host is connected the module will accept commands via USB.

USB BUS POWERED OPERATION MODE
The TMCM-1160 supports both, USB self powered operation (when an external power is supplied via the power supply connector) and USB bus powered operation, (no external power supply via power supply connector).
On-board digital core logic will be powered via USB in case no other supply is connected (USB bus powered operation). The digital core logic comprehends the microcontroller itself and also the EEPROM. The USB bus powered operation mode has been implemented to enable configuration, parameter settings, read-outs, firmware updates, etc. by just connecting an USB cable between module and host PC. No additional cabling or external devices (e.g. power supply) are required.
Please note that the module might draw current from the USB +5 V bus supply even in USB self powered operation depending on the voltage level of this supply.

Motor movements are not possible in this operation mode. Therefore, connect the power connector and change to USB self powered operation mode.

Jumpers

Most settings of the board are done through the software. Nevertheless, two jumpers are available for configuration.

Figure 4.1 RS485 and CAN bus termination

RS485 Bus Termination
The board includes a 120 Ohm resistor for proper bus termination of the RS485 interface. When this jumper is closed, the resistor will be placed between the two differential bus lines RS485+ and RS485-.

CAN Bus Termination
The board includes a 120 Ohm resistor for proper bus termination of the CAN interface. When this jumper is closed, the resistor will be placed between the two differential bus lines CAN_H and CAN_L.

Reset to Factory Defaults

It is possible to reset the PD-1160 to factory default settings without establishing a communication link. This might be helpful in case communication parameters of the preferred interface have been set to unknown values or got accidentally lost.
For this procedure two pads on the bottom side of the board have to be shortened (see Figure 5.1).

Figure 5.1 Reset to factory default settings

PERFORM THE FOLLOWING STEPS:

1. Power supply off and USB cable disconnected
2. Short two pads as marked in Figure 5.1
3. Power up board (power via USB is sufficient for this purpose)
4. Wait until the on-board red and green LEDs start flashing fast (this might take a while)
5. Power-off board (disconnect USB cable)
6. Remove short between pads
7. After switching on power-supply / connecting USB cable all permanent settings have been restored to factory defaults

On-board LED

The board offers two LEDs in order to indicate board status. The function of both LEDs is dependent on the firmware version. With standard TMCL firmware the green LED should be flashing during operation and the red LED should be off.
When there is no valid firmware programmed into the board or during firmware update the red and green LEDs are permanently on.

Functional Description

The TMCM-1160 is a highly integrated controller/driver module which can be controlled via several serial interfaces. Communication traffic is kept low since all time critical operations (e.g. ramp calculations) are performed on board. Common supply voltages are +12VDC / +24VDC / +48VDC. The module is designed for both, standalone operation and direct mode. Full remote control of device with feedback is possible. The firmware of the module can be updated via any of the serial interfaces.
In Figure 8.1 the main parts of the TMCM-1160 are shown:

• the microprocessor, which runs the TMCL operating system (connected to TMCL memory),
• the motion controller, which calculates ramps and speed profiles internally by hardware,
• the power driver with stallGuard2 and its energy efficient coolStep feature,
•  the MOSFET driver stage, and
• the sensOstep encoder with resolutions of 10bit (1024 steps) per revolution.

Figure 8.1 Main parts of the TMCM-1160

The TMCM-1160 comes with the PC based software development environment TMCL- IDE for the Trinamic Motion Control Language (TMCM). Using predefined TMCL high level commands like move to position a rapid and fast  development of motion control applications is guaranteed.
Please refer to the TMCM-1160 Firmware Manual for more information about TMCL commands.

TMCM-1160 Operational Description

Calculation: Velocity and Acceleration vs. Microstep and Fullstep Frequency
The values of the parameters sent to the TMC429 do not have typical motor values like rotations per second as velocity. But these values can be calculated from the TMC429 parameters as shown in this section.

PARAMETERS OF TMC429

Table 9.1 TMC429 velocity parameters

MICROSTEP FREQUENCY
The microstep frequency of the stepper motor is calculated with

FULLSTEP FREQUENCY
To calculate the full step frequency from the microstep frequency, the microstep frequency must be divided by the number of microsteps per full step.

The change in the pulse rate per time unit (pulse frequency change per second – the acceleration a) is given by

This results in acceleration in full steps of:
