FWD TQ
REV TQ
30 Calibration
The FWD TQ setting determines the maximum torque for accelerating and
driving the motor in the forward direction. It also sets the maximum torque
for decelerating the motor in the reverse direction. FWD TQ is factory set
at 120% of rated motor current.
If the time it takes to accelerate a load is too long due to the forward
torque setting, increase the forward torque setting to 130% of rated motor
current. The decision to change the forward torque setting must be made
after considering the gearbox and drivetrain ratings, duty cycle, and motor
characteristics. See Figure 16 for typical FWD TQ settings.
ATTENTION: Although FWD TQ is set to exceed the motor
nameplate current rating, continuous operation beyond that rating may
damage the motor.

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 optimum motor
regulation.
ATTENTION: Although REV TQ is set to exceed the motor
nameplate current rating, continuous operation beyond that rating may
damage the motor.
