5.5.1 Basic settings
To protect the drive system, the V/f control and the slip regulator must be commissioned
in several steps.
 Detailed information on the individual steps can be found in the following subchapters
or in the corresponding subchapters on V/f characteristic control.
 Tip!
Information on the optimisation of the control mode and the adaptation to the
real application is provided in the "Optimise control behaviour
" chapter on the V/f
characteristic control (VFCplus).

Parameterisable additional functions are described correspondingly in the
"Parameterisable additional functions
" chapter. ( 168)
Initial commissioning steps
1. Define the V/f characteristic:
• C00006
= 7: Linear characteristic
• C00006
= 9: Quadratic characteristic
2. Defining current limits (Imax controller)
. ( 115)
3. Parameterise the encoder/feedback system.

4. For special motors that have a rated frequency other than 50 Hz or a number of pole pairs ≠ 2: Set the motor
parameters according to the motor nameplate.

5. Specify the speed setpoint (e.g. 20 % of the rated speed) and enable the controller.
6. Check whether actual speed value (C00051
) ≈ speed setpoint (C00050) and inhibit the controller again
afterwards.
• Check the connection of the encoder if the signs of the actual value and the setpoint are reversed (e.g.
change track A or B of the encoder or invert the actual speed value).
• If the actual value and the setpoint differ strongly (factor 2), set the motor parameters according to the
motor nameplate. Then repeat step 5.
7. To protect the drive, reduce the slip regulator limitation in C00971/1
.
• E.g. reduce to half the slip frequency (≈ 2Hz)
8. Specify the speed setpoint (e.g. 20 % of the rated speed) and enable the controller.
9. If the operational performance is semi-stable, reduce the reset time (C00972
) or the proportional gain
(C00973
) of the slip regulator until stable operation is provided.
Parameterising the slip regulator
( 130)
10. Finally, increase the slip regulator limitation in C00971/1
again.
• E.g. increase to twice the slip frequency
