4.1 Introduction
MotiFlex
e
100 supports many feedback options for use with linear and rotary motors, including
incremental encoder, encoder with BiSS (Bi-directional Synchronous Serial interface), encoder
with SSI (Synchronous Serial Interface), EnDat absolute encoder or SinCos encoder. All suitable
types of feedback device can be connected to the universal feedback interface available on
connector 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
e
100 has
been designed so that motor feedback wiring enters the bottom panel of the drive, well away
from the AC power wiring entering the top panel.
H
Where feedback device wiring runs parallel to power cables, they must be separated by at
least 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 of
shields must often be insulated.
H
Linear motors may 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.
H
Baldor cables are recommended (see Appendix A). If alternative cables are used they must
be of an equivalent specification.
