Detail:
1.Two modes of speed regulation:
External potentiometer: through this potentiometer speed regulation;
External voltage: external 10VDC voltage speed regulation;
Note: The two speed regulation can not be used simultaneously
2. Speed output PG : There is a 5v-revolution pulse output between the port and the ground.
The output frequency is set to P (Hz), the motor class logarithm is N, and the speed is F (RPM), then the output speed frequency is P=F*N/60.
3. Alarm output ALM :There is an 5V alarm pulse output between the port and the ground.
4. Positive inversion function:
F/R:Fiddle the toggle switch on the corresponding side, the motor steering direction can be changed. For the toggle switch, the white part is up and down, then twang it up and down. For the toggle switch, the white part is horizontal, and the twang horizontally.

Package included:
1 x Motor Driver Controller with cable
