Incremental Encoder with Hall | 14 Jul 2014 | |

Incremental Encoder with Hall

Valid for S300, S400, S600, S700

Incremental encoders with Hall Sensors are a combination of incremental signals for positioning and Hall signals for commutation. The incremental signals can have 5V (TTL) level or 24V level. Encoders with Hall and 5V-TTL signals are called ComCoder.

This technology is common in the USA and coming up in Europe due to some advantages.

Advantages/Disadvantages of Comcoders


  • Resolution is higher than with a Resolver
  • Usually good price/performance ratio
  • No Wake and Shake required for commutation


  • With Kollmorgen servo amplifiers 15 pole feedback cables are required
    4 x incremental, 4 x power supply + sense, 3 x Hall, 2 x thermo, 2 x zero pulse 
  • not really usual in Europe
