Pattern
Description & Fault Type Cause Effect Solution
2121 2-3 Undervoltage Cutback
1. Batteries need
recharging. Controller is
performance limited at this
voltage
2. Battery parameters are
mis-adjusted.
Non-controller system-
drain on battery
3. Battery resistance too
high
4. Battery disconnected
while driving
5. Blown B+ fuse or main
contactor did not close

UnderVoltageCutback
See Programmer » System
Monitor menu » Controller
» Capacitor Voltage
Reduced drive
torque
Reduced regen
braking torque
Fault Action:
None, unless a fault
action is
programmed in VCL
Set: Capacitor bank voltage
dropped below the
UnderVoltageCutback limit with the
FET bridge enabled
Clear: Bring the capacitor voltage
above the controller’s
UnderVoltageCutback limit
2131 2-4 Overvoltage Cutback
1. Normal operation. Fault
shows that regen braking
currents elevated the
battery voltage during
regen braking. Controller is
performance limited at this
voltage
2. Battery parameters are
mis-adjusted
3. Battery resistance too
high for given regen current
4. Battery disconnected
while regen braking

Monitor menu » Controller
» Capacitor Voltage
Reduced brake
torque
Note: This fault is
declared only when
the controller is
running in regen
Fault Action:
None, unless a fault
action is
programmed in VCL
Set: The controller’s capacitor bank
voltage exceeded the
OverVoltageCutback limit with the
FET bridge enabled
Clear: Bring controller’s capacitor
voltage below the
OverVoltageCutback limit

Ext 5V Supply Failure
Ext_5V_Supply_Failure_Active
Fault Type(s):
1 = 5V Supply’s voltage is out-
of-range
2 = 5V Supply’s current is out-
of-range.
External load impedance
on the +5V supply is too
low
See the System Monitor »
Outputs menu:
External_5V_Supply,
Ext_5V_Current.
Disables the 5V
Supply
Fault Action:
None, unless a fault
action is
programmed in VCL.
Set:
(1) The 5V Supply is outside
5V±10%
(2) The current is outside limits
defined by:
Ext_5V_Supply_Min
Ext_5V_Supply_Max
Clear:
Reset Controller, or reset using the
VCL variable
