代碼 F00090: Encoder feedback loss

Reaction: OFF 2 Acknowledge: Quit fault eg. via DI2 Cause: Signal from Encoder lost (check fault value r0949): - r0949 = 0: Encoder signal lost. - r0949 = 1: Encoder loss detected due to sudden speed change (i.e. speed change detected on encoder in a single scan > value in P0492). - r0949 = 2: Encoder signal lost whilst running at low speed. - r0949 = 5: Encoder not configured in p0400, but required for sensored control (p1300 = 21 or 23). - r0949 = 6: Encoder not found, but configured in p0400. - r0949 = 7: Encoder loss detected due to motor stalled. Remedy: Stop the inverter. - r0949 = 2, Increase value of p0494 or reduce value of p1120 and p1121. - r0949 = 5, select encoder type via p0400. - r0949 = 5, select SLVC mode (p1300 = 20 or 22). - r0949 = 7, select SLVC mode (p1300 = 20 or 22). - 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.
