Installation

Do not install, rewire, or remove this control with input power applied. Doing so may cause damage or serious injury. Make sure you have read and understood the Safety Warnings section before attempting installation.

Speed adjust potentiometer

1. Enable (EN):

Close the enable to allow the motor to run at the speed set by the speed pot or input signal. Enable can control the motor stop and start.

2. Brake (BRAKE)

Close the brake terminals to brake the motor to the speed set by the MIN SPD trimpot. The amount of time the drive takes to brake the motor to MIN SPD is determined by the DECEL trimpot. The amount of braking Torque used to stop the motor is set by the REGEN CL trimpot. MIN SPD is typically set to zero speed.

3. Direction (DIR)

Close the direction terminals to change the motor direction.

4. Control mode for reference:

1. ACCEL (ACCELERATION)

Adjust the ACCEL trimpot to confirm the acceleration time which it takes from the original speed to desired speed (adjustable time is 0.2-20s) See diagram 5.

Turn the ACCEL trimpot CW to increase the acceleration time, and CCW to decrease the acceleration time.

2. DECEL (DECELERATION)

Adjust DCCEL potentiometer the motor to determine the speed of decline in the slope from the highest to the lowest speed (that is fall time, set time adjustable 0.2-20 seconds). See diagram 6.

Note: Adjust the DECEL trimpot until the desired deceleration time is reached. Turn the DECEL trimpot CW to increase the deceleration time, and CCW to decrease the deceleration time.

3. MIN SPD (MINIMUM SPEED)

The MIN SPD setting determines the motor speed when the speed adjust potentiometer is turned full CCW or when the BRAKE is closed. It is factory set for zero speed.

4. REV MAX SP (REVERSE DIRECTION MAX SPEED)

Adjust the REV MAX SP to send the REVERSE direction desired maximum speed (the function can be also used to limit the motors maximum speed). Rotate CW to raise the REVERSE direction speed.

5. FWD MAX SP (FORWARD DIRECTION MAX SPEED)

Adjust the FWD MAX SP to send the FORWARD direction desired maximum speed (the function can be also used to limit the motors maximum speed). Rotate CW to raise the FORWARD direction speed.

6. REGEN CL (REGENERATIVE CURRENT LIMIT)

The REGENERATIVE CURRENT LIMIT setting determines the maximum armature current available for braking. Set the REGEN CL based on the desired amount of braking. Slowly adjust the REGEN CL trimpot CW to raise the regenerative braking current.

7. MOTOR CURRENT LIMIT (MOTOR CL)

Adjust MOTOR CL potentiometer to limit the maximum output current, it is determined by motor rated current,. Please set suitable current, otherwise it will cause motor torque

Lose and the over-current protection. Adjust the MOTOR CL CW to raise output current.

The MOTOR CURRENT LIMIT setting determines the maximum armature current output of the drive.

8. IR COMPENSATION (IR COMP)

The IR COMP setting determines the degree to which motor speed is held constant as the motor load changes. It is factory set for no compensation.

Note: If the motor oscillates (overcompensation), the IR COMP trimpot may be set too high (CW). Turn the IR COMP trimpot CCW to stabilize the motor. And if the motors speed on load reduce, the IR COMP trimpot may be set too low.
