[Alarm Config]
A set of bits to enable/disable alarm conditions that will initiate a Converter alarm.
•
Bit 0 (Ac Low Volt) sets an alarm when the average AC line voltage is less than the limit in parameter 112 - [Low Vac Lmt].
•
Bit 1 (Ac High Volt) sets an alarm when the average AC line voltage exceeds the limit in parameter 114 - [High Vac Lmt].
•
Bit 2 (Ac Low Freq) sets an alarm when the AC line frequency is less than the limit in parameter 131 - [AC Low Freq Lmt].
•
Bit 3 (Ac High Freq) sets an alarm when the AC line frequency exceeds the limit in parameter 133 - [AC High Freq Lmt].
•
Bit 4 (Ac High dFdt) sets an alarm when the AC line frequency is changing faster than the limit in parameter 135 - [AC Maximum
dF/dt].
•
Bit 5 (I Imbalance) sets an alarm when the phase current imbalance exceeds the limit in parameter 103 - [I Imbalance Lmt].
•
Bit 6 (V Imbalance) sets an alarm when the phase voltage imbalance is greater than the limit in parameter 116 - [V Imbalance
Lmt].
•
Bit 7 (IT Overload) sets an alarm when the Overload counter is greater than 90%.
•
Bit 8 (Ambient Temp) sets an alarm when the ambient temperature exceeds the limit in parameter 120 - [Ambnt Temp Alrm].
•
Bit 9 (Base Temp) sets an alarm when the IGBT base temperature exceeds the limit in parameter 122 - [Base Temp Alrm].
•
Bit 10 (Junction Temp) sets an alarm when the IGBT junction temperature exceeds the limit in parameter 124 - [Junct Temp
Alrm].
•
Bit 11 (Coldplate Temp) sets an alarm when the coldplate temperature is less than the limit in parameter 126 - [CldPlt Temp
Alrm].
•
Bit 12 (PWM SyncLoss) sets an alarm when PWM carrier synchronization is lost.
•
Bit 15 (Start Inhibit) sets an alarm when one or more start inhibits are present.
