FEN-31 HTL Encoder Interface
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.
