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.
