FC 300 Design Guide
SSI encoder: Absolute
Encoder monitor:
The 4 encoder channels (A, B, Z, and D) are monitored, open and short circuit can be detected. There is
a green LED for each channel which lights up when the channel is OK.
NB!
The LEDs are only visible when removing the LCP. Reaction in case of an encoder error can
be selected in par. 17-61: None, Warning or Trip.
When the encoder option kit is ordered separately the kit includes:
• Encoder module MCB 102
• Enlarged LCP fixture and enlarged terminal cover
The encoder option does not support FC 302 frequency converters manufactured before week 50/2004.
Min. software version: 2.03 (par. 15-43)
