Basic settings
The following "Initial commissioning steps" must be performed to commission the servo control:
Tip!
Information on the optimisation of the control mode and the adaptation to the real
application is provided in chapter "
Parameterisable additional functions are described correspondingly in the chapter

Initial commissioning steps
1 Determine the motor control:
= "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 "
chapter.
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:
: Motor rotor resistance
: Motor stator resistance
: Motor stator leakage inductance
: Motor magnetising inductance
: Motor magnetising current
3. Define the type of control:
bTorquemodeOn
= FALSE:
Speed control with torque limitation
bTorquemodeOn
Torque control with speed limitation
4. Parameterise the encoder/feedback system.
5th Set the slip compensation (
Note!
• The Lenze settings of the inverter 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
. However, this also reduces the
maximum torque which is directly available after the setpoint enabling.
• If
= "0 %", magnetisation is not carried out.
