官方故障排除步驟
Message value: %1 Drive object: SERVO Reaction: NONE (OFF1, OFF2, OFF3) Acknowledge: IMMEDIATELY (POWER ON) Cause: One of the filter natural frequencies is greater than the Shannon frequency. The Shannon frequency is calculated according to the following formula: 0.5 / p0115[0] Fault value (r0949, interpret hexadecimal): Bit 0: Filter 1 (p1658, p1660) Bit 1: Filter 2 (p1663, p1665) Bit 2: Filter 3 (p1668, p1670) Bit 3: Filter 4 (p1673, p1675) Bit 8... 15: Data set number (starting from zero). Remedy: - reduce the numerator or denominator natural fr equency of the current setpoint filter involved. - reduce the current controller sampling time (p0115[0]). - switch out the filter involved (p1656).
