Power unit: Switching operations too frequent
converter
Meaning: The power unit has performed too many switching operations for current limiting. - Incorrect closed-loop control parameter settings. - Short circuit or ground fault in the motor. - V/f operation: The ramp-up time setting is too small. - V/f operation: The motor rated current is much higher than the power unit current. - Incorrect power cable connection. - Power cable exceeds the maximum permissible length. - Power unit damaged.

Power unit: Switching operations too frequent
converter
Meaning: %1 bin Component: Power unit. Broadcast: Local. Response: OFF2. Acknowledgment: Immediate. Cause: The power unit has performed too many switching operations for current limiting. - Incorrect closed-loop control parameter settings. - A short circuit or ground fault in the motor. - V/f operation: The set ramp-up time is too small. - V/f operation: The rated motor current is much higher than the power unit current. - Infeed: The discharge current and supplementary charging current are too large during a mains voltage dip. - Infeed: The supplementary charging current is too large during motor overload or a DC bus voltage dip. - Infeed: The power supply reactor is missing, resulting in a short-circuit current at switch-on. - Incorrect power cable connection. - The power cable exceeds the maximum permissible length. - The power unit is damaged.
