Enable
Close the enable to allow the motor to run at the speed set by the speed pot or input signal.
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.
Direction
Close the direction terminals to change the motor direction.
Note: In addition to dry contact inputs, the enable, brake and direction function also accept open col-
lector inputs. Rated at 0.5 mA or greater. See Figure 9.
