2 Parameters
2.2 List of parameters
p1570[0...n] CO: Flux setpoint / Flex setp
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL
Min
50.0 [%]
Description: Sets the flux setpoint referred to rated motor flux.
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: For p1570 > 100%, the flux setpoint increases as a function of the load from 100% (no-load operation) to the setting
in p1570 (above rated motor torque), if p1580 > 0% has been set.
p1571[0...n]

CI: Supplementary flux setpoint / Suppl flux setp

VECTOR_G (n/M) Can be changed: T
Data type: Unsigned32 / FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
-
Description: Sets the signal source for the supplementary flux setpoint.
Notice: Low flux setpoints can cause the drive to stall at higher loads. This is the reason that the flux setpoint should only be
adapted for slow load changes.
Note: The supplementary flux setpoint is limited to +/- 50 %.
p1572[0...n]

Supplementary flux setpoint / Suppl flux setp

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
0.0 [%]
Description: Sets the supplementary flux setpoint for the flux controller.
The value is referred to the rated motor flux.
Notice: The parameter should be set back to 0% again for normal closed-loop control operation.
Note: The parameter is used to optimize the flux controller. The current model is not influenced by the setting.
p1573[0...n]

Flux threshold value magnetizing / Flux thresh magnet

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PEM, REL
Min
10.0 [%]
Description: Sets the flux threshold value for enabling the speed setpoint and the end of magnetizing (r0056.4).
Note: The parameter only has an influence if the flux actual value reaches the threshold value p1573 more quickly during
magnetizing than the time set in p0346. This is generally the case when selecting fast magnetization (p1401 bit 6).
The parameter has no influence for flying restart (see p1200) and after DC braking (see p1231).
