p1584[0...n] Field weakening operation flux setpoint smoothing time / Field weak T_smth
Access level: 4 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6722
Min:
0 [ms] Max:
20000 [ms] Factory setting:
0 [ms]
Description: Sets the smoothing time for the flux setpoint in the field-weakening range
Recommendation: Smoothing should be especially used if there is no regenerative feedback into the line supply. This means that the DC
link voltage can quickly increase in regenerative operation
Note
Only the flux setpoint rise is smoothed
p1586[0...n] Field weakening characteristic scaling / Field weak scal
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
80.0 [%] Max:
120.0 [%] Factory setting:
100.0 [%]
Description: Sets the scaling of the precontrol characteristic for the start of field weakening.
For values above 100 % and for partial load situations, the field weakening starts at higher speeds.
Note
If the start of field weakening is shifted to lower speeds, then the voltage reserve is increased for partial load situations.
If the start of field weakening is shifted to higher speeds, the voltage reserve is appropriately reduced so that for fast
load changes, it can be expected that this will have a negative impact on the dynamic performance.
p1590[0...n] Flux controller P gain / Flux controller Kp
Access level: 4 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6723
Min:
0.0 Max:
999999.0 Factory setting:
10.0
Description: Sets the proportional gain for the flux controller.
Note
The value is automatically pre-assigned dependent on the motor when the drive system is first commissioned.
When calculating controller parameters (p0340 = 4), this value is re-calculated.
p1592[0...n] Flux controller integral time / Flux controller Tn
Access level: 4 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6723
Min:
0 [ms] Max:
10000 [ms] Factory setting:
30 [ms]
Description: Sets the integral time for the flux controller.
Note
The value is automatically pre-assigned dependent on the motor when the drive system is first commissioned.
When calculating controller parameters (p0340 = 4), this value is re-calculated.
