No. (Hex.) Name Description Default (Range) C4-01 (0215) RUN Torque Compensation Gain Sets the gain for the torque compensation function. Use this parameter value for motor 1 when operating multiple motors. Determined by A1-02 (0.00 - 2.50) For these control methods and states, adjust the setting value. A1-02 [Control Method Selection] Status Adjustment 0 [V/f Control] 8 [EZ Vector Control] Torque is not sufficient during low-speed operation of 10 Hz or less. Increase the setting in 0.05-unit increments. There is vibration in the motor or the motor hunts when operating the drive with a light load. Decrease the setting in 0.05-unit decrements. The cable length between the drive and motor is too long. Increase the setting in 0.05-unit increments. Note: Adjust C4-01 to make sure that output current is not more than the drive rated current while the drive operates at low speed. When A1-02 = 2 [Open Loop Vector], do not change this parameter under normal conditions. Torque accuracy will decrease. When A1-02 = 5 [PM Open Loop Vector], do not change this parameter under normal conditions. Setting this value too high can cause overcompensation and motor oscillation. When A1-02 = 8 [EZ Vector Control], you cannot change this parameter during drive run.
