Code A00590: Encoder feedback loss warning

Reaction: NONE Acknowledge: NONE Cause: Signal from Encoder lost; Inverter might have switched to sensorless vector control. Check also alarm value r0947: - r0949 = 0: Encoder signal lost. - r0949 = 5: Encoder not configured in P0400, but required for sensored control (P1300 = 21 or 23). Remedy: Stop inverter and then - Check encoder fitted. If encoder fitted and r0949 = 5, select encoder type via P0400. - If encoder fitted and r0949 = 6, check connections between encoder module and inverter. - If encoder not fitted and r0949 = 5, select SLVC mode (P1300 = 20 or 22). - If encoder not fitted and r0949 = 6, set P0400 = 0. - If encoder fitted, check correct encoder selected (check encoder setup in P0400). - Check connections between encoder and inverter. - Check that encoder not faulty (select P1300 = 0, run at fixed speed, check encoder feedback signal in r0061). - Increase encoder loss threshold in P0492.
