Wiring:
Use Slot B, for encoder interface, and I/O relay module (Left)
Reference attached manual for wiring instructions.
All wiring should match from encoder to encoder card pin-outs (A+, A-, B+, B-, Z, Z- ,V+)


Programming:

1. Configure the parameters of the encoder used
2. Configure the motor parameters.
3. Set Encoder usage [EnU] to [No] nO.
4. Perform auto-tuning.
5. Set Encoder check [EnC] to [Yes] YES
6. Run motor for a few seconds (Encoder check should change to done)
7. Set [Ctt] Motor control type to [FVC] Flux Vector Control

Use Encoder Check Procedure in the attached ATV900 Programming Manual for further assistance

*Key Notes:
-  Make sure wiring from encoder to encoder cards matches or else Encoder Check will not change to done.
-  If drive faults on SPF then check Encoder Card voltage pin-outs wiring and check [Encoder supply volt.] UeCv setting.
-  [Encoder check] ENC may stay stuck on yes unless you run the motor for a few seconds, minimum speed 10%, to synchronize the encoder card.
-  Encoder cards may use 9 or 15 pin adapter connections. Adapter connectors are not included with encoder cards.  May need to contact a 3rd party vendor.  DigiKey is one commonly used manufacturer.
-  Only available with the Altivar 900 and ATV340.  Encoder cards are not compatible with the ATV600 series drives.
