Motor Feedback (X8) - ABB MicroFlex e190 User Manual

76 Electrical installation: input / output

Motor feedback (X8)

MicroFlex e190 supports incremental encoder, EnDat 2.1, SinCos, BiSS-B (Bi-
directional Synchronous Serial Interface), SSI (Synchronous Serial Interface), EnDat
2.2, Smart Abs absolute encoder or Hiperface feedback, for use with linear and rotary
motors. Resolvers are supported by using the optional resolver adapter (see page
85). There are some important considerations when wiring the feedback device:
• The inputs are not isolated.
• The feedback device wiring must be separated from power wiring.
• Where feedback device wiring runs parallel to power cables, they must be
separated by at least 76 mm (3 in).
• Feedback device wiring must cross power wires at right angles only.
• To prevent contact with other conductors or earths / grounds, unearthed /
ungrounded ends of shields must often be insulated.
• 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 or the encoder breakout option (see page 180) can be used to
simplify linear feedback connections.
• A maximum combined total of 500 mA can be supplied by X8 pin 12 and X7 pin 9
to feedback devices. Self-resetting fuses protect the 5.5 / 8-12 V supply on X8
and the 5.5 V supply on X7.
