2.2 List of parameters
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
Description: Displays the output of the excitation current monitoring for separately excited synchronous motors.
Description: Sets the signal source for the individual feedback signals from the excitation.
Index: [0] = Excitation ready for switching on
[1] = Excitation ready
[2] = Excitation operational
[3] = Excitation group signal fault
[4] = Excitation group signal alarm
[5] = Not used
[6] = Not used
[7] = Excitation at the voltage limit
Dependency: Refer to: r1649
Description: Sets the monitoring time of the excitation.
After an ON command, the feedback signal must be received within this monitoring time.
Note: After the on command for the excitation (r1648.0 = 1), its feedback signal must be available at r1649.1 within this
monitoring time (BI: p1645[1]).
The same monitoring time is effective after the excitation is enabled for operation (r1648.3 = 1) up to the feedback
signal "excitation operational" (r1649.2 = 1, BI: p1645[2]).
