Cause : Resolver autotuning routines, which are automatically started when resolver input is activated for the first time, have failed.

Check cable between resolver and resolver interface module (FEN-21) and order of connector signal wires at both ends of cable. Check resolver parameter settings. For resolver parameters.

Note: Resolver autotuning routines should always be performed after resolver cable connection has been modified.

Autotuning routines can be activated by setting parameter 92.02 EXC SIGNAL AMPL or 92.03 EXC SIGNAL FREQ, and then setting parameter 90.10 ENC PAR REFRESH to (1) Configure.
