5.9.3 Basic settings
The following "Initial commissioning steps" must be performed to commission the servo control:
Initial commissioning steps
1. Determine the motor control:
• For the closed-loop control of a synchronous motor (PSM):
C00006 = "1: SC: Servo control PSM"
• For the closed-loop control of an asynchronous motor (ASM):
C00006 = "2: SC: Servo control ASM"
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
»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*
* Setting only required for asynchronous motors.
3. Define the type of control:
bTorquemodeOn = FALSE: Speed control with torque limitation
bTorquemodeOn = TRUE: Torque control with speed limitation
4. Parameterise the encoder/feedback system.  Encoder/feedback system ( 314)
5. Only with servo control for synchronous motors (PSM):
Detect pole position of the motor.  Pole position identification (PPI) ( 358)

Note!
• The Lenze settings of the controller are predefined for a power-adapted standard
asynchronous motor. For an optimal drive behaviour, we recommend to adapt the
controller settings.
• When controlling an asynchronous motor (ASM), magnetisation is carried out prior to
enabling the setpoint after a controller enable in the Lenze setting. The (delayed)
setpoint enabling ensures direct availability of the maximum torque at the motor.
• The delay of the setpoint enabling associated with the magnetisation can be
reduced by reducing the threshold set in C00918 . However, this also reduces the
maximum torque which is directly available after the setpoint enabling.
• If C00918 = "0 %", magnetisation is not carried out.
