Conversion of a Mitsubishi serial encoder to a TTL encoder

The Mitsubishi serial encoder transmits the information of its angular position in a purely serial way, therefore unlike other models (for example EnDAT) there are no sinusoidal signals.

The number of wires used is reduced: 4 wires for serial data and 2 wires for power. Serial data is transmitted and received by two pairs of balanced wires. The encoder is interrogated by the master unit and it provides the requested data: position, internal states, alarms and motor temperature.

My equipment only has TTL encoder input, what do I do?

This question was asked many times by our customers: some have the need to translate a resolver into a TTL encoder, others have to do it starting from a serial encoder, each has its own needs. For this reason our technical department has created a multifunction module able to be programmed to convert various types of transducers into a TTL encoder: among the various converter models we find the 13/013 “Serial encoder to TTL encoder converter“.

The Mitsubishi serial encoder and the 13/013 module

This module allows you to translate a Mitsubishi serial encoder into a TTL encoder with Hall sectors among the following:

  • OSA17.
  • OSA18-130.
  • HA300NC-S.
  • HC-SF.
  • HF303BS-A48.
  • For other models contact the technical service.

The output of module 13/013 will then be connected to a normal servoconverter with input for TTL encoder + Hall sectors (ours or third-party): it will thus be possible to operate the Mitsubishi brushless motor (permanent magnet synchronous) with any drive.

The 13/013 module is configured via the USB port connected to a PC software; most of the standard parameters are sufficient for operation, but you can customize some parameters to adapt the module to your equipment. In it there are also the following useful functions:

  1. Monitoring of serial data and communication with the Mitsubishi encoder, with anomaly signaling on digital output.
  2. Frequency / direction output for use with particular equipment.
  3. Adjustment of motor phasing vs. transducer.
