Precharge (Port 11) Faults
and Alarms (Frame 8 and
Larger) The table below contains a list of Precharge-specific faults and alarms, the type of
fault or alarm, the action taken when the drive faults, the parameter used to
configure the fault or alarm (if applicable), and a description and action (where
applicable). These faults and alarms only apply to Frame 8 drives and larger.

11301 P1 Precharge
P2 Precharge
P3 Precharge Alarm 1 The DC bus delta voltage (Vbus_in - Vbus_out) is greater than 25V
when the molded case switch (MCS) is open. This alarm is suppressed
when the Precharge Fault is present.
Resettable
Fault Coast The DC bus voltage did not meet all the conditions required to close the
molded case switch (MCS) within the timeout period.
1. DC bus input is not overvoltage
2. DC bus input is not undervoltage
3. DC bus delta voltage (Vbus_in - Vbus_out) is less than 25V

11315 P1 Bus Dip
P2 Bus Dip
P3 Bus Dip Alarm 1 Only occurs when the drive is offline or in stand-alone mode. The bus
voltage has dipped more than 180V below the drive’s bus memory. The
alarm is released when the bus voltage rises back to within 60V of the
drive’s bus memory.

11319 P1 240 V AC Loss
P2 240 V AC Loss
P3 240 V AC Loss Alarm 1 240V AC not present while the drive is in the inactive state. This alarm is
suppressed when the 240V AC Loss Fault is present.
Resettable
Fault Coast 240V AC was lost while in the active state. Active state whenever the
drive is not stopped, for example, the molded case switch (MCS) is
opening or closing or is closed.

11320 P1 240V AC Discon
P2 240V AC Discon
P3 240V AC Discon Alarm 1 The 240V AC disconnect is open when the precharge controller is in the
ready state (MCS is not closed).
11121

11321 P1 Bus Undervolt
P2 Bus Undervolt
P3 Bus Undervolt Alarm 1 The input bus voltage is below 400V DC while the molded case switch
(MCS) is open. Hysteresis level 420V DC. This alarm is suppressed when
the Bus Undervoltage Fault is present.
Resettable
Fault Coast The bus input voltage fell below 400V while the molded case switch
(MCS) was closed. Hysteresis level at 420V. The system SMPS cuts out
near 340V DC.
11122
11222
11322 P1 Bus Overvolt
P2 Bus Overvolt
P3 Bus Overvolt Alarm 1 The input bus voltage exceeds 820V DC. Hysteresis level 800V DC.

P2 MCS ShuntTrip
P3 MCS ShuntTrip Resettable
Fault Coast The molded case switch (MCS) auxiliary contact did not open within 1
second following the shunt trip coil activation.

P3 MCS CloseFail Resettable
Fault Coast The molded case switch (MCS) auxiliary contact did not close within 2
seconds following the close coil activation.

11332 P1 MCSAuxContact
P2 MCSAuxContact
P3 MCSAuxContact Resettable
Fault Coast The molded case switch (MCS) auxiliary contact was open when the MCS
was closed or closed when the MCS was open. If the MCS Failed to Close
Fault is present then this fault is not reported.
11133
11233
11333 P1 MCS Closed
P2 MCS Closed
P3 MCS Closed Resettable
Fault Coast The voltage across the molded case switch (MCS) when it was closed
exceeded 10V.
