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 to be powered-up
[1] = Excitation ready
[2] = Excitation operational
[3] = Excitation group signal fault
[4] = Excitation, group signal alarm
[5] = Not used
[6] = Not used
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 in operation" (r1649.2 = 1, BI: p1645[2]).
Description: Sets the switch-off delay time to shut-down the excitation equipment.
Note: The delay time starts if, when powering-down, r0863.0 = 0.
r1648.0 and r1648.3 are reset at the end of the delay time.
