Motor encoder connection X3A

The connection of the motor encoder is done on socket X3A. Which of the encoders can be connected depends
on the installed encoder interface and is displayed in LC.11.
All encoder connectors may be connected / discon-
nected only at switched off frequency inverter and
switched off supply voltage.
The frequency inverter monitores all encoder signals.
If the encoder alarm is activated and no zero track
is existent, connect N- with +5V (PIN12) and N+ with
COM (PIN13).
The encoder alarm can be switched off with LC.03.
