5.5.3 Basic settings
The following "Initial commissioning steps" must be performed to commission the sensorless vector
control:
 Tip!
We recommend to use the flying restart function for connecting/synchronising the inverter
to an already rotating drive system.Flying restart function

5.5.4 Optimise control behaviour
5.5.4.1 Optimising the starting performance after a controller enable
After the controller is enabled, a time delay is cause during the start due to the magnetisation of the
motor. If this delay cannot be tolerated for specific applications, the motor must always be operated
in an energised condition.
Procedure without setting a controller inhibit
1. Deactivate the auto-DCB function with C019
= 0.
2. Do not
activate the controller inhibit. Instead, stop the drive by selecting a setpoint of 0 or by
activating the quick stop function.
Initial commissioning steps
1. Set the motor selection/motor data
• When selecting and parameterising the motor, the motor nameplate data and the equivalent circuit di-
agram data are relevant. Detailed information can be found in the "Motor selection/Motor data
" chapter.
