• 1 Brake control output connector with 2 pins (orange mark)

NOTICE
Start with power supply OFF and do not connect or disconnect motor during operation! Motor cable and motor inductance might lead to voltage spikes when the motor is (dis)connected while energized. These voltage spikes might exceed voltage limits of the driver MOSFETs and might permanently damage them.
Therefore, always switch off / disconnect power supply or at least disable driver stage before connecting / disconnecting motor.
NOTICE
Take care of polarity, wrong polarity can destroy the board!
3.1 Screw Terminals
Mating cables are any cables with fitting M4 cable lugs.
NOTICE
Take care for using cables that fit to the required continuous current rating for your application!
NOTICE
Supply cable should be as short as possible to reduce cable resistance and limit voltage drop at high load on the supply.
NOTICE
Depending on your application make sure to add suficient capacitors to the driver input to stabilize driver supply.
Low ESR electrolyte caps are recommended, especially for higher current applications. See Section 4.1for more information on this.

Interface Circuits

4.1 Supply Connection and Supply Buffering
TMCM-1636 includes only limited onboard capacitance. For high current applications additional capacitors  must be placed close to the module power input to stabilize power supply. In addition, a regulatedpower supply is highly recommended.
NOTICE
Depending on your application make sure to add suficient capacitors to the driver input to stabilize supply.
Low ESR electrolyte caps are recommended.
A maximum supply ripple of 0.25V (TBD) is allowed.
It is recommended to connect electrolytic capacitors of significant size to the power supply lines close to the TMCM-1636 !
Rule of thumb for size of electrolytic capacitor: C = 1000 μF/A ….ISUP P LY
The capacitors should be selected with regard to high ripple current rating.
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.
4.2 General Purpose Inputs
The four general purpose inputs are optically isolated with opto-couplers. All GPI share the same COM connection.![TRINAMIC TMCM-1636 Single Axis Servo Drive

• General Purpose Inputs](https://manuals.plus/wp-content/uploads/2023/09 /TRINAMIC-TMCM-1636-Single-Axis-Servo-Drive-General-Purpose-Inputs.jpg)A separated / isolated supply may be used for the inputs – as indicated in the drawing (+24V_ISO and related GND_ISO) – but, same supply as for the TMCM- 1636can be used as well.
  4.3 General Purpose Outputs
  The two general purpose outputs are simple open drain outputs using n-channel FETs.
  The gates of the n-channel FETs are pulled low.
  There are no flyback diodes on the TMCM-1636. 4.4 Analog Inputs
  The two analog inputs go through a voltage divider and a simple filter before connecting to the microcontroller’s ADC inputs.
  The analog inputs allow for a 5V input range.
  The input filter has a cut-off frequency of ca. 285Hz.
  4.5 Reference Inputs
  TMCM-1636 provides three reference inputs: Left, Right, and Home.
  The nput voltage range is 0V…5V.
  The inputs have an internal pull-up to 5V.
  An input filter has a cut-off frequency of ca. 34kHz
  4.6 Brake Control Output
  The brake control output BRAKE is a PWM controlled low-side output for driving solenoids. The drive current is configurable up to 1A.
  4.7 Over-Voltage Protection Output
  The over-voltage protection output OVP is a low-side output for external brake resistor. It can be used to prevent the supply rail from exceeding the maximum rated values in case of overvoltage conditions.
  4.8 Feedback Interfaces
  4.8.1 Incremental Quadrature Encoders 1 & 2
  TMCM-1636 provides two incremental quadrature encoder interfaces with A, B, and N signals each.
  The input voltage range is 0V…5V.
  The encoder inputs have an internal pull-up to 5V.
  An input filter has a cut-off frequency of ca. 1.6MHz.
  4.8.2 Digital Hall Sensors
  TMCM-1636 provides a Hall signal interface.
  The input voltage range is 0V…5V.
  The Hall inputs have an internal pull-up to 5V.
  An input filter has a cut-off frequency of ca. 4kHz.
  4.8.3 SPI-based Absolute Encoder
  TMCM-1636 provides an SPI master interface for external absolute position sensors or other peripherals (with custom firmware option).
  The SPI interface runs at 5V signal level.
  4.8.4 RS422-based Absolute Encoder
  TMCM-1636 provides an RS422 interface for external absolute position sensors that use SSI or BiSS interface (depends on firmware option or custom firmware).
  TMCM-1636 integrates the RS422 transceiver (TI THVD1451DRBR).
  The incoming RS422 data line (SSI_ENC_DATA_P and SSI_ENC_DATA_N) has an onboard termination of 120R.

LED Status Indicators

The TMCM-1636 has two on-boards LED status indicators.

Communication

The following sections give some guidelines and best practices when setting up the communication bus systems supported by TMCM-1636.
6.1 CAN
For remote control and communication with a host system the TMCM-1636 provides a CAN bus interface.
For proper operation the following items should be taken into account when setting up a CAN 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.       

2. BUS TERMINATION:
   Especially for longer buses and/or multiple nodes connected to the bus and/or high communication speeds, the bus should be properly terminated at both ends. The TMCM-1636 does not integrate any termination resistor. Therefore, 120 Ohm termination resistors at both ends of the bus have to be added externally.

3. BUS TERMINATION:
   The bus transceiver used on the TMCM-1636 units or on the base board (TJA1042TK/3) supports at least 110 nodes under optimum conditions. Practically achievable number of nodes per CAN bus highly depend on bus length (longer bus -> less nodes) and communication speed (higher speed -> less nodes).

Operational Ratings and Characteristics

7.1 Absolute Maximum Ratings

NOTICE
Stresses above those listed under “‘Absolute Maximum Ratings”’ may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

7.2 Operational Ratings
Ambient temperature 25° C, if not stated otherwise.

7.3 I/O Ratings
Ambient temperature 25° C, if not stated otherwise.

1. This is the maximum current rating. This is not for continuous operation but depends on motor type, duty cycle, ambient temperature, and active/passive cooling measures.
2. Working at high environmental temperatures may require additional cooling measures depending on duty cycle and maximum current/power draw.
