コード 230001: <location>Power unit: Overcurrent

Message value: Fault cause: %1 bin Drive object: All objects Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: The power unit has detected an overcurrent condition. - closed-loop control is incorrectly parameterized. - motor has a short-circuit or fault to ground (frame). - V/f operation: Up ramp set too low. - V/f operation: Rated motor current is significantly greater than that of the Motor Module. - infeed: High discharge and post-charging cu rrent for line supply voltage interruptions. - infeed: High post-charging currents for over load when motoring and DC link voltage dip. - infeed: Short-circuit currents at power-on due to the missing commutating reactor. - power cables are no t correctly connected. - power cables exceed the maximum permissible length. - power unit defective. Additional causes for a parallel switching device (r0108.15 = 1): - a power unit has tripped (powered down) due to a ground fault. - the closed-loop circulating current control is either too slow or has been set too fast. Fault value (r0949, interpret bitwise binary): Bit 0: Phase U. Bit 1: Phase V. Bit 2: Phase W. Note: Fault = 0 means that the phase with overcurrent is not recognized (e.g. for Blocksize device). Remedy: - check the motor data - if required, carry out commissioning. - check the motor circuit configuration (star-delta). - V/f operation: Increase up ramp. - V/f operation: Check the assignment of the rated currents of the motor and Motor Module. - infeed: Check the line supply quality. - infeed: Reduce the load when motoring. - infeed: Correct connection of the line commutating reactor. - check the power cable connections. - check the power cables for short-circuit or ground fault. - check the length of the power cables. - replace power unit. For a parallel switching device (r0108.15 = 1) the following additionally applies: - check the ground fault monitoring thresholds (p0287). - check the setting of the closed-loop circulating current control (p7036, p7037).
