SINAMICS G120 Control Units CU240S, Edition 05/2007
Note: Safety Integrated: If driving loads occur in the application, the motor must be dimensioned so that its slip in super-
synchronous operation always remains within the rated slip.
Description: Nominal motor current [A] from rating plate - see diagram in P0304.
Dependency: Changeable only when P0010 = 1 (quick commissioning).
Depends also on P0320 (motor magnetization current).
Note: The maximum value of P0305 depends on the maximum inverter current r0209 and the motor type:
Asynchronous motor : P0305_max = P0209
Synchronous motor : P0305_max = 2 * P0209 (for HO operation) and P0305_max = P0209 (for LO operation)
It is recommended that the ratio of P0305 (rated motor current) and r0207 (rated inverter current) should not be
lower than:
When the relation of the nominal motor current P0305 and half of the maximal inverter current (r0209) exceeds 1.5
an additional current derating is applied. This is necessary to protect the inverter from harmonic current waves.
Default value is depending on inverter type and its rating data.
