This PM45 FH stepper motor driver is specifically designed for manually controlling bipolar steppe motors.
There are two different types of connectors it can fit in, 1.25mm pitch and 2.0mm connectors.
When the driver is connected with 3~12 V DC power supply(VDD connected to positive of power supply, and GND is connected to negative.), it’s able to driver a regular stepper motor.
There are four buttons on the driver panel, and user can click different button combinations, to control a stepper motor with demanded order.
Four buttons:
(R: run; S: stop; A: Acceleration; D: Deceleration )
Button combination:
| Number | Button combination | Function description |
| 1 | A = ON | When the motor is at a standstill, press the accelerator key, and the motor will start to run forward manually; |
| 2 | A+R= ON | When the motor is at a standstill, press the acceleration + run key, and the motor will start to manually accelerate forward; |
| 3 | A+S = ON | When the motor is at a standstill, press the acceleration + stop button, and the motor will start manual forward deceleration operation; |
| 4 | D = ON | When the motor is at a standstill, the deceleration key is pressed and the motor starts to run in reverse manually; |
| 5 | D+R= ON | When the motor is at a standstill, press the deceleration + run key, and the motor will start manual reverse acceleration operation; |
| 6 | D+S = ON | When the motor is at a standstill, press the deceleration + stop button, and the motor will start manual reverse deceleration operation; |
| 7 | R = ON | When the motor is at a standstill, press the run button and the motor will start to run automatically; |
| 8 | A = ON | When the motor is running automatically, press the accelerator key and the motor will start to accelerate; |
| 9 | D = ON | When the motor is running automatically, when the deceleration key is pressed, the motor starts to decelerate; |
| 10 | R+A= ON | When the motor is running automatically, press the run+accelerator key, and the motor will start to run automatically in the forward direction; |
| 11 | R+D= ON | When the motor is running automatically, press the run + slow down key, and the motor will start to run automatically in the reverse direction; |
| 12 | S+A(S+D) = ON | When the motor is stationary, press the stop+acceleration (or stop+decelerate) key, and the motor starts to manually set the distance of automatic cycle running; |
| 13 | S+R= ON | When the motor is at a standstill, press the stop + run key, and the motor will automatically reciprocate according to the manually set distance; |
| 14 | A= ON | When the motor is running in a reciprocating cycle, press the accelerator key, and the motor will accelerate in a reciprocating cycle; |
| 15 | D= ON | When the motor is running in a reciprocating cycle, press the deceleration key, and the motor will decelerate in a reciprocating cycle; |
| 16 | R+A= ON | When the motor is running in a reciprocating cycle, press the run+accelerator key, and the motor will reciprocate in a forward direction; |
| 17 | R+D= ON | When the motor is running in a reciprocating cycle, press the run + deceleration key, and the motor will reciprocate and run in the reverse direction; |
| 18 | S = ON | When the motor is running, press the stop button to stop the motor. |
| Remark | Combination keys, press in the order given, then it can reach its function. | |
