2.2 List of parameters
r1641

Excitation current actual value / I_exc_act val

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
- [%]
Description: Displays the excitation current actual value that is read in.
Dependency: Refer to: p0390
p1642[0...n]

Minimum excitation current / Min I_exc

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
0.1 [%]
Description: Sets the minimum excitation current.
This means that negative excitation currents can be avoided.
p1643[0...n] Minimum excitation current closed-loop control gain factor / I_exc_min Kp
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
Description: Sets the gain factor for the minimum excitation current, closed-loop control.
This is active if the excitation current is below 75 % of p1642.
Dependency: Refer to: p1642
r1644

CO: Excitation current monitoring output / I_exc_monit outp

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
- [Arms]
Description: Displays the output of the excitation current monitoring for separately excited synchronous motors.
p1645[0...7] BI: Excitation feedback signals signal source / Exc FS S_src
VECTOR_G (n/M) Can be changed: T
Data type: Unsigned32 / Binary
P-Group: Commands
Not for motor type: ASM, PEM, REL
Min
-
Description: Sets the signal source for the individual feedback signals from the excitation.
