Integer
Indicates the occurrence of conditions that have been configured as alarms.
Bit 0 “IGBT OT” – Indicates the transistor (IGBT) junction temperature reached the alarm level, which is 10 °C (50 °F) below the maximum (fault level) junction
temperature.
Bit 1 Heatsink OT” – Indicates the heatsink temperature reached the alarm level, which is 10 °C (50 °F) below the maximum (fault level) heatsink temperature.
Bit 2 “Waking” – The Sleep /Wake function is in the Waking condition.
Bit 3 “StartOnPwrUp” – The Start on powerup feature is active.
Bit 4 “Drive OL” – Indicates overload condition has reached the alarm level and P940 [Drive OL Count] has reached 50%.
Bit 5 “CurLmt Reduc” – Indicates the transistor (IGBT) junction temperature reached the level of current limit fold back, which is 5 °C (41 °F) below the maximum
(fault level) junction temperature.
Bit 6 “PWMFrq Reduc” – Indicates the transistor (IGBT) junction temperature reached the level of PWM frequency fold back, which is 10 °C (50 °F) below the
maximum (fault level) junction temperature. Or the instantaneous rising of junction temperature exceeded 60 °C (140 °F).
