SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
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
4: U/f control with linear characteristic and ECO
7: U/f control for a parabolic characteristic and ECO
20: Speed control (encoderless)
Dependency: Only operation with U/f characteristic is possible if the rated motor speed is not entered (p0311).
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. In
the case of analog setpoints, if required the tolerance for ramp-up and ramp-down should be actively increased for
the ramp-function generator using p1148 in order to reliably signal a steady-state condition.
Note: During operation (the pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing
over drive data sets.
