Product Usage Instructions
Description
The PULSER is a programmable motion path generator/controller designed to
manage simple motion paths by generating STEP/DIR/ENA control signals. It
works in conjunction with a motor drive to control the motor’s position.
Motion Path Generation
The trapezoidal speed profile is utilized for generating motor motion
paths. Parameters like acceleration, deceleration, maximum STEP pulse
frequency, number of pulses, and direction of movement are considered.
Motion Control
To control motor positioning, activate digital input lines via buttons or a
basic purpose PLC.
Programming
Programming the PULSER is straightforward using the provided software. The
programmed sequences are stored in the EEPROM memory on the microcontroller.
Movement Path Selection
Select the programmed movement path for the motor using one of the seven
inputs from IN1 to IN7. Upon receiving a pulse at the selected input, program
execution begins, and the Busy output is activated. The Busy output
deactivates upon program completion.
Error Handling
If an error occurs during program execution, control pulse generation
halts, and the motor driver stops. The Error output is activated, and the
OP/ER LED flashes.

A: Connect the PULSER to the motor drive using appropriate connectors based on the available connectors and PULSER connection information provided in the user manual. -
Q: Can I use external buttons to trigger program execution?
A: Yes, external buttons can be used to trigger program execution by generating pulses at the selected input for work program activation.
DESCRIPTION
PULSER is a programmable motion path generator/controller and it is intended for managing the execution of simple motion paths by generating STEP/DIR/ENA control signals. It is used together with the motor drive to control position of the motor (Figure 1.1). The trapezoidal speed profile is used to generate motor motion path. This means that PULSER takes into account the set of parameters, such as: acceleration, deceleration, maximum frequency of STEP pulses, number of pulses, direction of movement, etc. Control of the motor positioning is reduced to activating the digital input lines by means of buttons or via a basic purpose PLC. Programming the PULSER is very easy with the free software. The programmed sequences are stored in the EEPROM memory on board microcontroller. The selection of the programmed movement path for motor is made through one of the seven inputs for selection of the work program, inputs from IN1 to IN7. Upon the arrival of a pulse at one of the inputs for selecting the work program, the execution of the program is started and the “Busy” output is activated. The pulse can be generated by an external button or by an external PLC. When the program is finished, the “Busy” output is deactivated. In this way, PULSER signals that it has completed the execution of the program and is ready for the next activation of one of the programs. If an error occurs during the execution of the program, the generation of control pulses is interrupted, that is, the motor driver will stop. In this case, the “Error” output will be activated and the “OP/ER” LED will flash.

AVAILABLE CONNECTORS AND PULSER CONNECTION
Figure 3.1 shows connectors position on Pulser. For programming the Pulser, it is recommended to use the isolation interface for programming IPI-USB, which is connected to the Pulser via the programming port (Figure 3.1), and to the PC via the USB connector.
Figure 3.2 and Figure 3.3 provide recommended Pulser wiring diagrams
.

lines (IN1 – IN8)
Figure 3.3 Recommended wiring diagram for the case when the input lines (IN1 –
IN8) are powered directly from the Pulser power line
IMPORTANT NOTE: It is necessary to place jumpers J1 and J2 in their
positions
LED indicators on Busy and Error lines is optional.
CONFIGURATION SOFTWARE
The configuration software is used to define the programs that are assigned to the active keys IN1-IN7. The selection of available programs is classified into tabs – groups of choices (Figure 4.1):
- Switch function,
- Analog speed control,
- Inc/Dec control and
- Jog with speed control.
Programming of the PULSER is done using Windows configuration software which is available for free on www.audiohms.com. For programming, you need to connect the computer and the PULSER with a standard USB A/B cable, which is used to connect a computer and a USB printer. After programming the PULSER,the connection to the PC is no longer needed and the PULSER can work independently. The PULSER configuration is stored on onboard microcontroller EEPROM memory.
Choice “Switch function”
The Switch function group (Figure 4.2 – Switch function tab) provides the
possibility that each of the seven program selection inputs, IN1-IN7, can be
independently associated with any of the following programs:
- Go,
- Go&Return,
- Go while pressed,
- Go until stop and
- Go until limit.
The eighth input IN8 (Stop) is used to stop the program that is currently
being executed.
Each of the inputs can be activated independently. If the execution of the
previously activated program is in progress, PULSER will not accept the
activation of the next program.
It is possible to realize from one to seven movement programs. If the user
only needs one program, he will configure and activate only one input. If it
needs two programs, it will configure and activate two inputs, etc.
Program “Go”
Program “Go” (Figure 4.2) is used to generate the desired number of STEP pulses. Upon arrival of the activation signal on input, STEP and DIR control signals are generated. Parameters that could be adjusted are: Acceleration, deceleration, maximum pulse generation frequency, direction of rotation, total number of generated steps, number of repetitions and duration of pause between repetitions.
Program “Go &Return”
The “Go&Return” program generates an exact number of STEP pulses in one and
then in the other direction of rotation (Figure 4.3). Upon the arrival of the
input control signal, STEP pulses are generated to one direction, a pause is
made and the generation of control STEP pulses to the opposite direction is
continued. Acceleration and deceleration, the total number of generated steps
in one direction, the duration of the pause, the total number of generated
motor steps in the opposite direction, the maximum frequency of generation of
STEP pulses during movement in one or the opposite direction, the number of
repetitions and the duration of the pause between repetitions are set.
The “Go while pressed” program (Figure 4.4) generates STEP pulses as long as a positive voltage is present at the program selection control input. Acceleration, deceleration, direction of rotation and maximum frequency of STEP pulse generation are set.
Program “Go while pressed”
If the “Go until stop” program is selected, when a positive pulse arrives at the selected control input, the STEP pulses is generated until a positive pulse is applied to the IN8-STOP input (Figure 4.5). After that, the generation of STEP pulses slows down. Acceleration, deceleration, direction of rotation and maximum frequency of STEP pulse generation are parameters to be set.
Program “Go until stop”
If the “Go until stop” program is selected, when a positive pulse arrives at
the selected control input, the STEP pulses is generated until a positive
pulse is applied to the IN8-STOP input (Figure 4.5). After that, the
generation of STEP pulses slows down. Acceleration, deceleration, direction of
rotation and maximum frequency of STEP pulse generation are parameters to be
set.
Program “Go until limit”
The “Go until stop” program (Figure 4.6) is suitable motor referencing – taking the starting position. The limit switch is connected to the input IN8-STOP. When a positive pulse appears at the program selection input, a control STEP pulses are generated in one direction until the limit switch is activated. After that, a STEP pulses are generated in the opposite direction until limit switch is deactivated when motor decelerates and stops. Acceleration, deceleration, direction of rotation, maximum frequency of generation of STEP pulses in one direction and in the opposite direction are parameters to be set.
Program “Analog speed control”
The “Analog speed control” mode is available by selecting the corresponding
tab in the configuration software (Figure 4.7).When a positive pulse appears
at the program selection input (Start switch – Figure 4.7), the control STEP
pulses are generated, where the frequency of the pulse depends on the voltage
level at the analog input of the Pulser and the set of parameters. The maximum
frequency of STEP pulse generation, acceleration/deceleration, Threshold zone,
the input that activates movement and the initial direction of rotation are
parameters to be set. The recommended way to generate an analog signal is via
a potentiometer. Figure 3.2 shows the position of connectors for wiring the
potentiometer to the Pulser.
The “Analog speed control” program provides the option of turning the engine in one direction (Forward – Figure 4.7) or in both directions (Forward/Reverse – Figure 4.8).
Program “Inc/Dec speed control”
The “Inc/Dec speed control” program is available in the associated tab
selection in the configuration software (Figure 4.9). In this operating mode,
the digital inputs for Start (IN1), Increment (IN2), Decrement (IN3) and Stop
(IN8) are fixed. The dialog gives the possibility to set: the maximum
frequency of STEP pulses, the increase (increment) of the number of
revolutions, the initial frequency of STEP pulses, as well as the
acceleration/deceleration during the change of the frequency of STEP pulses.
It is possible to set whether the motor will turn in one direction (Forward)
or in both directions (Forward/Reverse).
Program “Jog with speed control”
“Jog with speed control” control mode (Figure 4.10) is similar to the Jog mode on CNC machines. The motor is started via two buttons (first for one direction and second button for the other direction), while the movement speed is defined via an analog input (potentiometer). The dialog gives the possibility to set: maximum frequency of STEP pulse generation, acceleration/deceleration during the change of STEP pulse frequency, selection of inputs that will activate the movement of the motor in one or the other direction, as well as the inactive zone (Threshold) of the analog input.
