SINAMICS G120C
142 List Manual (LH13), 04/2014, A5E33840768B AA
Description: Displays the actual output of the Vdc controller (DC link voltage controller)
Description: Sets the open and closed-loop control mode of a drive.
Value: 0: U/f control with linear characteristic
1: U/f control with linear characteristic and FCC
2: U/f control with parabolic characteristic
3: U/f control with parameterizable characteristic
4: U/f control with linear characteristic and ECO
5: U/f control for drives requiring a precise freq. (e.g. textiles)
6: U/f control for drives requiring a precise frequency and FCC
7: U/f control for a parabolic characteristic and ECO
19: U/f control with independent voltage setpoint
20: Speed control (encoderless)
Dependency: Only operation with U/f characteristic is possible if the rated motor speed is not entered (p0311).
Operation with a U/f characteristic is not supported for 1LE4 synchronous motors.
Refer to: p0300, p0311, p0500
Notice: Active slip compensation is required in the U/f control types with Eco mode (p1300 = 4, 7). The scaling of the slip
compensation (p1335) should be set so that the slip is completely compensated (generally 100%).
The Eco mode is only effective in steady-state operation and when the ramp-function generator is not bypassed.
Note: For the open-loop control modes p1300 = 5 and 6 (textile sector), slip compensation p1335, resonance damping
p1338, and the Imax frequency controller are switched off internally so that the output frequency can be set precisely.
The Imax voltage controller remains active.
During operation (pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing over
drive data sets.
Description: Sets the configuration for the U/f control.
Note: Re bit 03:
When the bit is set, when the drive stops, the starting frequency of the motor holding brake is also not fallen below
when the actual slip frequency is less than the starting frequency.
Re bit 04:
Field orientation for the closed-loop control of the basis application. The field orientation is activated with the
automatic calculation if p0096 is set = 1.
