[Start Inhibit]
A set of bits displaying the interlocks that inhibit the Converter from starting.
•
Bit 0 (Ac Low Volt) is set when the average AC line voltage is less than the limit in parameter 112 - [Low Vac Lmt].
•
Bit 1 (Ac High Volt) is set when the average AC line voltage exceeds the limit in parameter 114 - [High Vac Lmt].
•
Bit 2 (Ac Low Freq) is set when the AC line frequency is less than the limit in parameter 131 - [AC Low Freq Lmt].
•
Bit 3 (Ac High Freq) is set when the AC line frequency exceeds the limit in parameter 133 - [AC High Freq Lmt].
•
Bit 4 (Single Phase) is set when an input phase is missing.
•
Bit 5 (Phased ACB) is set when an input phase voltage is phased ACB and parameter 051 - [Option Select] Bit 0 (AutoPhaseRot)
is not enabled.
•
Bit 6 (DC Link Low) is set when DC Link voltage is too low to close the precharge bypass contactor.
•
Bit 7 (High dv/dt) is set when DC Link dv/dt is too high to close the precharge bypass contactor.
•
Bit 8 (Pchg Open) is set when the precharge bypass contactor is open and manual sequencing is selected.
•
Bit 9 (PWM Not Sync) is set when Par 051 - [Option Select] Bit 3 (PWM SyncRecv) is turned on and synchronization is not completed.
•
Bit 10 (Reqst Maintd) is set after a fault if the enable is not turned off. Restart requires a rising edge.
•
Bit 11 (High DC Link) is set when Run On PwrUp is selected in parameter 50 - [Start Config] and the DC Link is greater than
1.44 times the value in parameter 114 - [High Vac Lmt]. On a 480 volt unit, parameter 114 - [High Vac Lmt] defaults to “528” so
inhibit Bit 11 (High DC Link) defaults to 760 volts.
•
Bit 15 (Faulted) is set when the Converter is faulted.
