  • Page 11: Overview

    Overview Overview This chapter contains a short description of the FEN-01 TTL Encoder Interface. The FEN-01 TTL Encoder Interface The FEN-01 offers an interface for two TTL encoder connections, one with commutation signals and PTC support. It also offers a TTL encoder output for emulation purposes and two digital latch inputs for position latching.

  • Page 12: Compatibility

    The shields of sockets X31 and X32 and plug X33 are connected to chassis. The fixing screw connects the chassis to ground. Compatibility FEN-01 is compatible with the following encoders. • TTL incremental encoder, 1…65535 pulses / rev, supports reference mark •...

  • Page 13: Installation

    Installation Warning! Follow the safety instructions given in this guide and in the drive’s hardware manual. Setting the supply voltage Warning! Selecting the wrong supply voltage may damage or break the encoder. A selectable supply voltage is provided for the TTL encoders’ input.

  • Page 14: Mounting

    Note: Before mounting the module, set the supply voltage jumpers as described above. The FEN-01 is to be inserted into the option slot of the drive. See the drive hardware manual for more information. The module is held in place with plastic retaining clips and one screw.

    DI_2- Latch signal 2 return Encoder wiring The encoders should be connected to the FEN-01 with a shielded instrumentation cable, preferably with twisted pairs. See also the encoder manual for additional requirements. To prevent the encoder inputs from being disturbed, the cable shield must be connected to the chassis.
