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 ". ( 167)
We recommend to use the flying restart function for connecting/synchronising the inverter
to an already rotating drive system.  Flying restart function ( 208)
Parameterisable additional functions are described correspondingly in the chapter
" Parameterisable additional functions ". ( 202)

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. ( 105)
Depending on the motor manufacturer, proceed as follows:
Lenze motor:
Selecting a motor from the motor catalogue in the
»Engineer«
- 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 ( 215)
