12. Adaptable motor
The controller is adaptable to squirrel-cage asynchronous motor or AC PMSM. Select a
proper controller according to motor nameplate.
The default parameters configured inside the controller are squirrel-cage asynchronous
motor parameters. It is still necessary to perform motor auto-tuning or modify the
default values based on actual conditions. Otherwise, the running effect and protection
performance will be affected. For PMSM, motor auto-tuning must be performed.
13. Precautions on selecting residual-current circuit breaker (RCCB)
Tripping may be caused if an improper RCCB is selected when the controller drives
the motor. This is because the output wave of the controller has high harmonics and
the motor cable and the cable connecting the controller and the motor produce leakage
current, which is much larger than the current when the motor runs at the mains
frequency.
Thus, it is necessary to determine the proper RCCB sensitivity based on the general
leakage current of the cables and the motor. The leakage current is dependent on the
motor capacity, cable length, insulation class and wiring method. Generally, the leakage
current on the output side of the controller is three times of the current when the motor
runs at the mains frequency.
