Alarms
135 [Alarm Config]
Enables/disables alarm conditions that will initiate an AFE alarm.
• Bit 0 (Prechrg Actv) sets an alarm when the precharging is not completed.
• Bit 1 (DC UnderVolt) sets an alarm when the DC link voltage exceeded the limit.
• Bit 2 (Anlg In Loss) sets an alarm when the analog input is lost.
• Bit 3 (LineSyncFail) sets an alarm when the AC input line phase is missing.
• Bit 4 (HeatsinkOvTp) sets an alarm when the heatsink temperature is over temperature (90 °C).
• Bit 5 (LCL Fan Stop) sets an alarm when the LCL fan has been stopped.
• Bit 6 (DCRefLowLim) sets an alarm when the DC voltage reference is less than the limit in parameter 080 [DC Ref Lo Lmt].
• Bit 7 (DCRefHighLim) sets an alarm when the DC voltage reference exceeds the limit in parameter 081 [DC Ref Hi Lmt].
• Bit 8 (DCBusLoAlarm) sets an alarm when the DC voltage is less than the value set by parameter 078 [DC Bus Lo Alarm].
• Bit 9 (DCBusHiAlarm) sets an alarm when the DC voltage exceeds the value set by parameter 079 [DC Bus Hi Alarm].
