A145 alarm in WEG CFW900 Drive indicates an SNTP Connection Timeout. This means the drive attempted to synchronize its internal clock but received no response from the configured NTP server.
Cause:
It indicates that the inverter tried to connect to the NTP server and got no response. It occurs when, for some reason, after starting connection with the NTP server, the server did not return the response requested by the inverter.
- Incorrect configuration and IP address.
- Targeted NTP server is no longer active.
Remedy:
Check configuration and IP address. Verify that the NTP server is still active and reachable over the network.
