The ABB Encoder Interface Board FEN-31 is a specialized electronic component designed to interface with ABB encoders for motion control applications. This board serves as a communication interface between the encoder and the control system, allowing for accurate position feedback and control of motor movements. The FEN-31 board is compatible with various types of ABB encoders and can be easily integrated into existing control systems for precise and reliable motion control.
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.
