p1574[0...n]

Voltage reserve dynamic / U_reserve dyn

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.0 [Vrms]
Description: Sets a dynamic voltage reserve.
Note: In the field weakening range, it must be expected that the control dynamic performance is somewhat restricted due to
the limited possibilities of controlling/adjusting the voltage. This can be improved by increasing the voltage reserve.
Increasing the reserve reduces the steady-state maximum output voltage (r0071).
p1575[0...n]

Voltage target value limit / U_tgt val lim

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: REL
Min
50.00 [%]
Description: Sets the limit of the voltage target value.
In steady-state field weakening operation this corresponds to the required output voltage.
The value of 100% refers to p0304.
Note: The output voltage is only limited if the maximum output voltage (r0071) minus the voltage reserve (p1574)
corresponds to a value higher than p1575.
Limiting via p1575 allows the influence of the voltage ripple of the line supply voltage to be eliminated at the operating
point.
p1576[0...n]

Flux boost adaptation speed, lower / Flux boost n lower

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
0.00 [rpm]
Description: Sets the lower adaptation speed of the flux boost.
Below this speed, p1570 is set as reference (setpoint) flux.
p1577[0...n]

Flux boost adaptation speed upper / Flux boost n upper

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
1.0 [%]
Description: Sets the upper adaptation speed of the flux boost.
Above this speed, the rated motor flux (100 %) is set as reference (setpoint) flux.
Dependency: The parameter value refers to the lower adaptation speed of the flux boost.
