官方故障排除步驟
Message value: %1 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: KTY: The motor temperature has exceeded the fault threshold (p0604 or p0616). VECTOR: The response parameterized in p0610 becomes active. PTC: The response threshold of 1650 Ohm was exceeded. Alarm value (r2124, interpret decimal): SME not selected in p0601: 1: No output current reduction. 2: Output current reduction active. SME selected in p0601 (p0601 = 10): The number specifies the sensor channel that resulted in the alarm being output. See also: p0604 (Motor overtemperature alarm th reshold), p0610 (Motor overtemperature response) Remedy: - check the motor load. - check the motor ambient temperature. - check KTY84.
