X8 Resolver Feedback The r esolver connections are the standard feedback on Flex+ drives and
connections are made at the X8 connector as shown in Figure 3-27. The resolver
cable must be shielded twisted pair #22 AWG (0.34mm
2
) wire minimum. The
cable must also have an overall shield. Maximum wire-to-wire or wire-to-shield
capacitance is 50pf per foot.
Resolver wiring must be separated from power wiring. Separate parallel runs of
resolver and power cables by at least 3'. Cross power wires at right angles only.
Insulate or tape ungrounded end of shields to prevent contact with other
conductors or ground.
Note: Motor and resolver are phase sensitive. Connect only as instructed.
