Feedback Cables

General

Technical data of feedback cables depend on the used cable material. US cables have different data from EU cables.

Differences are especially:

  • Temperature range
  • Cable diameter
  • Bending radius
  • Insulation material

It is strongly recommended to use cables configured by Kollmorgen to avoided bad contacting, wrong pinout and EMC problems.

Part Number Scheme

Since 2012 the part number scheme helps with identifying the European cables.
Order codes for cables defined prior to 2012 and information for configuring cables can be found in the Accessories Manual.

Configured Feedback Cables

Kollmorgen delivers mating connectors as well as configured cables in various lengths with mounted mating connectors.
Different feedback systems (see MultiFeedback) require different cable versions.

Technical Data for Kollmorgen Feedback Cables

The table describes the minimum requirements which the european Kollmorgen cables comply with. Single data of the delivered cables can be better than the data given below, but they will never be worse.
