Section 1General Information3-8 Installation MN1230Resolver Feedback The resolver connections are made at the J2 connector as shown in Figure 3-4. Theresolver cable must be shielded twisted pair #22 AWG (0.34mm2) wire minimum. Thecable 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 7500pffor 150 ft). See electrical noise considerations in Section 5 of this manual.Resolver wiring must be separated from power wiring. Separate parallel runs of resolverand power cables by at least 3″. Cross power wires at right angles only. Insulate or tapeungrounded 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 thecontrol 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.Figure 3-4 Resolver Cable ConnectionsP1 SIN+6 SIN–2 COS+7 COS–3 REF+8 REF– (Common)13 AGNDPPP= Twisted PairR2R1S2S4S1S3J2
