IPA is reporting E37 Bad Hall State errors with an absolute encoder:
By default the IPA drive's encoder input is configured for an incremental encoder. The drive does not auto-detect the feedback type on power cycle. Parameter C171 indicates the feedback type.
C171=1 Incremental Encoder
C171=2 Endat Absolute
This parameter requires a power cycle or REBOOT to take effect. The correct value for C171 is included in the motor data downloaded via ACR-View.
Use the STATUS command in the terminal to verify the feedback type.
