官方故障排除步驟

Message value: Drive object: SERVO, VECTOR Reaction: OFF1 (NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: For a configured linear axis/no modulo axis, the currently effect ive motor encoder (encoder 1) has exceeded the maximum possi ble traversing range. For the configured linear axis, the maximum trav ersing range is defined to be 64x (+/- 32x) of p0421. It should be read in p2721 and interpreted as the number of load revolutions. Note: Here, only the motor encoder in the currently effective drive data set is monitored. The currently effective drive data set is displayed in x = r0051 and the corresponding motor encoder is specified in p0187[x]. Remedy: The fault should be resolved as follows: - select encoder commissioning (p0010 = 4). - reset position tracking, position (p2720.2 = 1). - de-select encoder commissioning (p0010 = 0). The fault should then be acknowledged and the absolute encoder adjusted. SINAMICS-Alarms
