官方故障排除步骤
Message value: %1 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: After the drive system is powered up, the synchr onization between the basic clock cycle, DRIVE-CLiQ clock cycle and application clock cy cle was started but was not completed within the selected time tolerance. Alarm value (r2124, interpret decimal): Only for internal Siemens troubleshooting. SINAMICS-Alarms Remedy: Carry out a POWER ON (power off/on) for all components. If the error occurs after the drive sampling times we re adjusted, and if a TM31 module is being used, the sampling times (p0115, p4099) should be set as integer multiples to the driv e clock cycles (p0115).
