NOTICE
The MCB 103 can be used with only rotor-supplied
resolver types. Stator-supplied resolvers cannot be used.
LED indicators
The LEDs are active when parameter 17-61 Feedback Signal
Monitoring is set to [1] Warning or [2] Trip.
LED 1 is on when the reference signal is OK to resolver.
LED 2 is on when Cosinus signal is OK from resolver.
LED 3 is on when Sinus signal is OK from resolver.
