Feedback 4-1MN1942

4.1 Introduction

MicroFlex e100 supports many feedback options for use with linear and rotary motors, including

incremental encoder , encoder with SSI (Synchronous Serial Interface), SinCos encoder , or

EnDat absolute encoder . All suitable types of feedback device can be connected to the universal

feedback interface available on connector X8.

There are some important considerations when wiring the feedback device:

H The feedback device wiring must be separated from power wiring.

H Where feedback device wiring runs parallel to power cables, they must be separated by at

least 76mm (3 in)

H Feedback device wiring must cross power wires at right angles only.

H To prevent contact with other conductors or earths/grounds, unearthed/ungrounded ends of

shields must often be insulated.

H Linear motors use two separate cables (encoder and Hall). The cores of these two cables will

need to be wired to the appropriate pins of the 15-pin D-type mating connector.

H The inputs are not isolated.
