官方故障排除步骤
Message value: Fault cause: %1 bin Drive object: SERVO, VECTOR Reaction: ENCODER (IASC/DCBRAKE, NONE) Acknowledge: PULSE INHIBIT Cause: The DRIVE-CLiQ encoder supplies status informati on via bits in an internal status/fault word. Some of these bits cause this fault to be triggered. Other bits are status displays. The status/fault word is displayed in the fault value. Fault value (r0949, interpret binary): Bit 0: F1 (safety status display) Bit 1: F2 (safety status display) Bit 2: Lighting (reserved) Bit 3: Signal amplitude (reserved) Bit 4: Position value (reserved) Bit 5: Overvoltage (reserved) Bit 6: Undervoltage (reserved) Bit 7: Overcurrent (reserved) Bit 8: Battery (reserved) Bit 16: Lighting (--> F3x135, x = 1, 2, 3) Bit 17: Signal amplitude (--> F3x135, x = 1, 2, 3) Bit 18: Singleturn position 1 (--> F3x135, x = 1, 2, 3) Bit 19: Overvoltage (--> F3x135, x = 1, 2, 3) Bit 20: Undervoltage (--> F3x135, x = 1, 2, 3) Bit 21: Overcurrent (--> F3x135, x = 1, 2, 3) Bit 22: Temperature exceeded (--> F3x405, x = 1, 2, 3) Bit 23: Singleturn position 2 (safety status display) Bit 24: Singleturn system (--> F3x135, x = 1, 2, 3) Bit 25: Singleturm power down (--> F3x135, x = 1, 2, 3) Bit 26: Multiturn position 1 (--> F3x136, x = 1, 2, 3) Bit 27: Multiturn position 2 (--> F3x136, x = 1, 2, 3) Bit 28: Multiturn system (--> F3x136, x = 1, 2, 3) Bit 29: Multiturn power down (--> F3x136, x = 1, 2, 3) Bit 30: Multiturn overflow/underflow (--> F3x136, x = 1, 2, 3) Bit 31: Multiturn battery (reserved) Remedy: Replace DRIVE-CLiQ encoder.
