FEN-31 HTLEncoderInterface

FEN-31 is an interface between the control board and an HTL encoder. It supports

various types of HTL encoders. A PTC, Pt1000 or KTY temperature sensor can be

attached to one of the connections of the FEN-31 interface.

FEN-31 offers an RS-422-standard-compliant TTL encoder emulation output and two

digital inputs. It also includes cable fault diagnostics for some HTL encoder types.

See the drive Firmware manual for details.
