This parameter is to set rated slip of loaded motor. Users need to input rated rotation speed according to nameplate of loaded motor. If rated frequency of motor is 60Hz, number of motor poles is 4 and rated rotation speed of motor is 1650rpm. The rated slip frequency of motor is
This parameter has relation with
07 - 06 | Auto Torque Compensation Gain | Unit: 0.1 | |
| Settings | 0.0~10.0 | Factory Setting: 0.0 |
|
|

|
This parameter is to set auto torque compensation gain.
When motor loading is high, a part of output frequency of AC drive will be absorbed by impedance of stator winding to make voltage of exciting inductance of motor is not enough. Therefore, the short of gap magnet field will make a high output current but low output torque. Auto torque compensation gain could adjust output voltage automatically according to loading to maintain in a fixed gap magnet of the motor to get the best running situation.
If the setting of compensation gain is too great,
07 - 07 | Torque Compensation Gain by Manual Operation | Unit: 1.0 | |
| Settings | 0.0~10.0 | Factory Setting: 0.0 |
|
|
|
|
This parameter determines torque compensation gain by manual operation.
Torque compensation gain by manual operation won’t refer to the loading situation and adds compensation voltage on the setting V/f curve. Basically, it just changes V/f curve. It could be reached by adjusting V/f curve.
07 - 08 | Calculate Total Running Time of the Motor (Min) | Unit: 1 | |
| Settings | 00 to 1439 Min | Factory Setting: 00 |
07 - 09 | Calculate Total Running Time of the Motor (Day) | Unit: 1 | |
| Settings | 00 to 65535 Day | Factory Setting: 00 |
