5.7.3 Basic settings
The following "Initial commissioning steps" must be performed to commission the sensorless vector
control:
 Tip!
Information on the optimisation of the control mode and the adaptation to the real
application is provided in chapter "Optimising the control mode
". ( 198)
We recommend to use the flying restart function for connecting/synchronising the inverter
to an already rotating drive system.Flying restart function

Initial commissioning steps
1 Determine the motor control:
C00006
= "4: SLVC: Vector control"
2. Set the motor selection/motor data
• When selecting and parameterising the motor, the motor nameplate data and the equivalent circuit
diagram data are relevant. Detailed information can be found in the "Motor selection/Motor data
"
chapter. ( 135)
Depending on the motor manufacturer, proceed as follows:
Lenze motor:
Selecting a motor from the motor catalogue in the

- or -
1.Set the motor nameplate data
2.Automatic motor data identification
Third party manufacturer's motor:
1.Set the motor nameplate data
2.Automatic motor data identification
or set known
equivalent circuit diagram data manually:
C00082
: Motor rotor resistance
C00084
: Motor stator resistance
C00085
: Motor stator leakage inductance
C00092
: Motor magnetising inductance
C00095
: Motor magnetising current
3. Define the type of control:
bTorquemodeOn = FALSE: Speed control with torque limitation
bTorquemodeOn = TRUE: Torque control with speed limitation
4. Set the slip compensation (C00021). Slip compensation ( 271)
