3.29.2 Field-orientated vector control
P1400[3] Configuration of speed control Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 1
P-Group: CONTROL Active: Immediately QuickComm.: No Max: 3
Configuration for speed control.
Bitfields:
Bit00 Automatic Kp adaption 0 NO 1 YES
Bit01 Integral freeze (SLVC) 0 NO 1 YES
Index:
P1400[0] : 1st. Drive data set (DDS)
P1400[1] : 2nd. Drive data set (DDS)
P1400[2] : 3rd. Drive data set (DDS)
Note:
P1400 Bit 00 = 1:
Automatic gain adaption of speed controller is enabled. In the area of field weakening the gain is reduced in
dependence on flux.

P1400 Bit01 = 1:
The integrator of the speed controller is frozen if Sensorless Vector Control (SLVC) is selected and the
control is switched from closed-loop to open-loop operation.
Advantage:
The correct amount of slip compensation is calculated and applied to the open-loop function for a motor
under load.
r1407 CO/BO: Status 2 of motor control Min: -
Datatype: U16 Unit: - Def: -
P-Group: CONTROL Max: -
Displays status of motor control, which can be used to diagnose inverter status.
Bitfields:
Bit00 V/f control enable 0 NO 1 YES
Bit01 SLVC enable 0 NO 1 YES
Bit02 Torque control enable 0 NO 1 YES
Bit05 Stop I-comp. speed control 0 NO 1 YES
Bit06 Set I-comp. speed controller 0 NO 1 YES
Bit08 Upper torque limit active 0 NO 1 YES
Bit09 Lower torque limit active 0 NO 1 YES
Bit10 Enable droop 0 NO 1 YES
Bit15 DDS change active 0 NO 1 YES
Details:
See P052 (CO/BO: Status word 1)
