官方故障排除步驟
Message value: Parameter: %1 Drive object: SERVO Reaction: NONE Acknowledge: IMMEDIATELY Cause: Encoderless operation is not possible for the selected pulse frequency (p1800). Encoderless operation is activat ed under the following conditions: - the changeover speed for encoderless operation (p1404) is less than the maximum speed (p0322). - a control type with encoderless operation has been selected (p1300). - encoder faults of the motor encoder result in a fault response with encoderless operation (p0491). See also: p0491, p1300, p1404, p1800 Remedy: Increase the pulse frequency (p1800). Note: In encoderless operation, the pulse frequency must be at least as high as half the current controller clock cycle (1/p0115[0]).
