Qué Significa el Fallo

Alarm: Encoder feedback loss warning

Causas probables

• r0949 = 0: Encoder signal lost.
• r0949 = 5: Encoder not configured in P0400, but required for sensored control (P1300 = 21 or 23).
• 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.
