2120
1-7 Severe B+
Undervoltage
1. Non-controller system
drain on battery
2. Battery resistance too
high
3. Battery disconnected
while driving
4. Blown B+ fuse or main
contactor did not close
5. Battery parameters are
mis-adjusted
See Programmer » Monitor
menu » Controller »
Capacitor Voltage
No drive torque.
Fault Action:
ShutdownPump
ShutdownMotor
Dual Drive
This Motor:
TrimDisable
Other Motor:
TrimDisable
Set: When Main is closed and the FET
Bridge is enabled, either the undervoltage
drive current cut back = 0% for 64 ms or the
Brownout Voltage is reached
Clear:
Undervoltage drive current cut back > 0%
for 100 ms and capacitor voltage >
brownout voltage
2122
1-7 Severe KSI
Undervoltage
1. Non-controller system
drain on battery/keyswitch
circuit wiring
2. Resistance in low power
(KSI) circuit is too high
3. KSI disconnected while
driving
Blown fuse
See Programmer » System
Monitor menu » Battery »
Keyswitch Voltage
Fault Action:
ShutdownAll
Set: When below Brownout Voltage for
2 seconds
Clear: Bring KSI voltage above Brownout
Voltage
2130
1-8
Severe B+
Overvoltage
1. Battery parameters are
misadjusted
2. Battery resistance too
high for given regen current
3. Battery disconnected
while regen braking
