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
