SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Parameter to select the control method.
Controls relationship between speed of motor and voltage supplied by inverter as illustrated in the diagram below.
Values: 0: V/f with linear characteristic
1: V/f with FCC
2: V/f with quadratic characteristic
3: V/f with programmable characteristic
4: reserved
5: V/f for textile applications
6: V/f with FCC for textile applications
19: V/f control with independent voltage setpoint
20: Sensorless vector control
21: Vector control with sensor
22: Sensorless vector torque-control
23: Vector torque-control with sensor
Dependency: See parameter P0205, P0500
Caution: When commissioning Vector Control with encoder-feedback (VC), the drive should be configured for V/f mode (see
P1300) first.
Run the drive and compare r0061 with r0021 that should agree in
• sign and
• magnitude (with a deviation of only a few percent).
Only if both criteria are fullfilled, change P1300 and select VC (P1300 = 21 or 23).
P0400 = 1 (single channel encoder) will only allow operation in one direction.
If operation in both directions is required, connect an encoder with 2 channels (A and B) and select setting 2.
See the Operating Instructions of the encoder module for more information.
