Caution: The input of rating plate data must correspond with the wiring of the motor (star / delta). This means, if
delta wiring is used for the motor, delta rating plate data has to be entered.

Note: Following diagram shows a typical rating plate with the locations of the relevant motor data.
P0305[0...2] Rated motor current [A] 0.01 -
10000.00
1.86 C(1) - DDS Float 1
Nominal motor current from rating plate.
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
It is recommended that the ratio of P0305 (rated motor current) and r0207 (rated inverter current) should
not be lower than: (1 / 8) <= (P0305 / r0207)
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.
