◆Torque mode
Description: Set initial torque automatical compensation function.
Cd03=0 Automatic torque compensation de-active, set boost by Cd07.
Cd03=1 Initial torque boost active, set maximum boost by Cd07.
◆Torque compensation gain
Description: Torque compensation is automatic function of increasing torque when the load of motor is
detected too high. To measure the resistant of motor is demanded to use this function. Please use the
automatic measure of motor or input known the resistant of motor
CE86。
Setting precaution:
1. Frequency torque compensation will run when operation freauency exceeds Cd60 which be set
2. Increase the value of Cd59 when unload current is too large, opposite when too small to collocate Cd60.
3. Increase gain of C4-01 when motor start and the torgue is not enough.
4. Over current occurred when start, please decrease gain of Cd07.
5. Current exceed rated current when motor idled, and decrease gain of Cd07.
6. Vibration occurred when motor rotated, and decrease gain Cd07 or increase delay time Cd50.
7. Please collocate with slip compensation when operated rated speed under 3Hz is demanded.
8. Torque compensation is invalid when the resistant of motor is CE86=0 or torque compensation gain
Cd07=0, operated by set V/f curve.
