Resolver Feedback

3-8 Installation
The resolver connections are made at the J2 connector as shown in Figure 3-4. 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.
Caution: Do not connect any shields to the motor frame. At a minimum,
resolver signal integrity will be compromised and damage to the
control may result.
1. Connect the SIN+ to J2-1 and SIN– to J2-6.
2. Connect the COS+ to J2-2 and COS– to J2-7.
3. Connect the REF+ to J2-3 and REF– to J2-8.
4. Connect the analog ground wire to J2-13.
