Starting behavior

The starting behavior of the machine can be configured. In Configuration 110 (V/f control of asyn-
chronous motor) the starting behavior can be set via parameter
In the field-orientated control method of configurations 410 (asynchronous motor) and 610 (synchro-
nous motor), the starting behavior can be set via the limits

The parameter
Operation mode
"110 - IM: sensorless control" (V/f control of asynchronous motor) is selected. Depending on the op-
eration mode selected, the motor is magnetized first or a starting current is impressed. The voltage
drop across the stator resistance which reduces the torque in the lower frequency range can be com-
pensated by the IxR compensation.
To ensure the correct function of the IxR compensation, the stator resistance is determined during the
guided commissioning (Setup). The IxR compensation is only activated when the stator resistance was
determined correctly.
