All suitabletypes of feedback device can be connected to the universal feedback interface available onconnector X8 (bottom panel).There are some important considerations when wiring the feedback device:H The feedback device wiring must be separated from power wiring. The MotiFlex e100 hasbeen designed so that motor feedback wiring enters the bottom panel of the drive, well awayfrom the AC power wiring entering the top panel.H Where feedback device wiring runs parallel to power cables, they must be separated by atleast 76 mm (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 ofshields must often be insulated.H Linear motors may use two separate cables (encoder and Hall). The cores of these twocables will need to be wired to the appropriate pins of the 15-pin D-type mating connector.H The inputs are not isolated.H Baldor cables are recommended (see Appendix A). If alternative cables are used they mustbe of an equivalent specification.4 Feedback 4
