官方故障排除步驟

Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF1 (NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: When powered down, the drive/encoder was moved through a distance greater than was parameterized in the tolerance window. It is possible that t here is no longer any reference between the mechanical system and encoder. Fault value (r0949, decimal): Deviation (difference) to the last encoder position in increments of the absolute value. The sign designates the traversing direction. Note: The deviation (difference) found is also displayed in r0477. See also: p0413 (Measuring gear, position tracking tolerance window), r0477 (Measuring gear, position difference) Remedy: Reset the position tracking as follows: - select encoder commissioning (p0010 = 4). - reset the position tracking as follows (p0411.2 = 1). - de-select encoder commissioning (p0010 = 0). The fault should then be acknowledged and, if neces sary, the absolute encoder adjusted (p2507). See also: p0010, p2507
