Note
Tripped Pre-charge Circuit Breaker Occurrences
The pre-charge circuit breaker shall be tripped if any of the following occurs:
• Over-voltage (>115%) occurs during pre-charge
• Under-Voltage Trip (PCVMRStatus_O)
• Input Protection Fault
• LFR Trip
• PB4/E-Stop
• M2 Contactor Open Status Failure
• Trip_CB2 (TripPrechargeCB2_O) is asserted
The SOP input control 󹪞ags below are available for particular cell types using the pre-charge
function by selecting Type 4 pre-charge. No dedicated inputs are used.

TripPrechargeCB2_O (SOP) TripPrechargeCB2 Request trip of pre-charge CB
PCVMRStatus_O PCVMRStatus Precharge voltage (CB UV trip) status - '1' = voltage okay
CB2Status_O CB2Status Precharge CB status - '1' = CB is closed
There are 16 digital outputs on the 󹪝rst user I/O board:
• DO-0 to DO-15
There is one digital output on the system interface board:
• SIB M1 DOUT

If this signal is de-energized, the drive’s medi‐
um voltage will trip immediately.
If the signal is not energized, it will be an in‐
hibit.
