Overview
This chapter contains a short description of the FEN-31 HTL
Encoder Interface.
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 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.
