Basic Installation 3-21MN1902
3.7 Feedb ack connectio n s
Two feedback options are available for use with linear and rotary motors - commutating
encoder or resolver . Confirm the catalog number of your FlexDrive
II
(see section 2.2.1) to
ensure you are wiring the correct feedback device. 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 be insulated.
H Some larger D- type connector shells may be obstructed by neighboring connector X3.
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
(supplied).
An encoder output signal is available on connector X7 for supplying other equipment.
FlexDrive
II
models with the resolver option provide a simulated encoder output, while the
encoder based FlexDrive
II
duplicates the encoder signals entering X8. See section 4.4.1 for
details.
