官方故障排除步骤
Parameters: %1 = Number of parameter the value of which is to be written. %2 = Value to be written %3 = Area (drive object class to which the write job was addressed) %4 = Time passed without the write j ob being acknowledged by the drive unit. Definitions: The write job of a SINAMICS parameter was not not acknowledged within 10 seconds by the drive unit. If the write job is not acknowledged within the nex t 10 seconds, the alarm will again be triggered. The waiting period for the acknowledgement of a write job is a maximum of 130 seconds, i.e. if the timeout specified in the alarm is 1 30 seconds, it is assumed that the write job has failed. Otherwise it can be assumed that the write job wa s successful despite the timeout. Reaction: Alarm display. Remedy: As long as the timeout specified in the alarm is less than 130 seconds, acknowledge alarm, otherwise switch off/on control, drive system and HMI, and then repeat the process leading to the alarm.
