IMPULSE•G+ Mini Advanced Instruction Manual – March 2014
5-36
When more torque is needed, increase the torque compensation gain in one-tenth (0.1) increments.
Increase the setting when the wiring distance between the inverter and the motor is 100ft. or longer. If
the motor generates excessive vibration or oscillates, decrease the torque compensation.
Increasing torque compensation gain increases motor torque, but an excessive increase may cause the
following:
• Inverter fault trips due to motor overexcitation and/or
• Motor overheat or excessive vibration
Increase the torque compensation time constant in 10ms increments when the motor’s output current is
unstable. Decrease this value when speed response is slow.
