Use the potentiometer to control the motor speed

Use the analog signal to control the motor speed

                                                                                                                                                                                                                             

Function of Control Terminal

1.BRAKE
Regenerative braking control: When quick stopping of motor is required, this function is suitable. Close brake switch, motor controller rapidly brakes motor’s speed by the way of regenerative braking then make motor stop immediately.

2.EN
Enable control: Control the start and stop of motor

3.DIR:
The reversing control of motor: Rotation direction can be easily get through open or close reversing switch.              

                                                                                                                                                                                       

Analog Quantity Control

You can control this motor speed by analog quantity signal 0-5V

Instruction and setting of adjustable potentiometer

1. “ACCEL” potentiometer( Set soft start time 0.2s - 20s )
Adjust “ACCEL” potentiometer to set ramp up from initial speed value to setting speed value(it means acceleration time)


2. “DECEL” potentiometer( Set soft stop time 0.2s - 20s )
Adjust “DECEL” potentiometer to set ramp down from Max.speed value to Min.speed value(it means deceleration time).

3. “FWD MAX SP"

Set the MAX forward speed.

4. “REV MAX SP”

Set the MAX reverse speed.

5. “REGEN CL”
Adjust “REGEN CL” potentiometer to limit Max. braking armature current value(it also means brake/stop time). The braking current value affect brake/stop time.

6. “IR COMP”
Adjust “IR COMP” potentiometer to make motor have constant speed value in different load conditions( factory setting is ”0”).

7. “MIN SP”

Set the motor MIN speed

8. “MOTOR CL”
Adjust “MOTOR CL”potentiometer to limit motor controller’s Max.output current(we also say motor’s setting current value).The setting of this current should be based on motor’s rated current value.Current value should be moderate.If not,torque is not enough or overcurrent protection is failure. Adjust this potentiometer in clockwise to increase motor controller’s output current.
Note: Motor controller’s output current value should be twice as much as motor’s rated current value in general.However,motor controller can’t  operate at setting value which is greater than motor’s rated current value for a long time, or the motor will be burnt out.
