官方故障排除步驟
Message value: Fault cause: %1, channel number: %2 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: When evaluating the temperature sensor, an error occurred. Alarm value (r2124, interpret decimal): Low word low byte: Cause: 1: Wire breakage or sensor not connected (KTY: R > 1630 Ohm). 2: Measured resistance too low (PTC: R < 20 Ohm, KTY: R < 50 Ohm). Additional values: Only for internal Siemens troubleshooting. Low word high byte: Channel number. See also: p0491 (Motor encoder fault response ENCODER) Remedy: - check that the encoder cable is the correct type and is correctly connected. - check the temperature sensor selection in p0600 to p0603. - replace the Sensor Module (hardwar e defect or incorrect calibration data).
