3. Pin Assignment and Description
The driver has two connectors namely P1 & P2, Connector P1 for control signals connection, Connector P2
for power and motor connections. The following tables are brief descriptions of the two connectors

RPM & DIRECTION Control by Rotary Wheel and Switch
1. Clockwise and Anticlockwise movement of Rotary wheel will give Clockwise
and
Anticlockwise motion of motor.
2. To increase speed continue to rotate the wheel in same direction.
3. Once desired speed is achieved press the switch once to record the data,the motor will stop.
4. Now you can use the switch for ON-OFF as per requirement and the saved data will be used
to rotate the motor.
5. Long press of 5 Sec or more will erase old data.
6. Repeat steps 1 to 4 for saving new data.
Wiring Notes
To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should
not be tied up together. It is better to separate them by at least 10 cm, otherwise the disturbing signals
generated by motor will easily disturb pulse direction signals, causing motor position error, system
instability and other failures.
If a power supply serves several drivers, separately connecting the drivers is recommended instead of
daisy-chaining.
It is prohibited to pull and plug connector P2 while the driver is powered ON, because there is high
current flowing through motor coils (even when motor is at standstill). Pulling or plugging connector
P2 with power on will cause extremely high back-EMF voltage surge, which may damage the driver.
