The resolver connections are made at the J1 connector as shown in Figure 3-23. The
resolver cable must be shielded twisted pair #22 AWG (0.34mm
cable must also have an overall shield and not exceed 150 feet (45m) in length.
Maximum wire-to-wire or wire-to-shield capacitance is 50pf per foot (maximum of 7500pf
for 150 ft). See electrical noise considerations in Section 5 of this manual.
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.
