OVERVOLTAGE CUT-
BACK
Check battery wires and
connections; Check fuse state
and main contact connections.
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 misadjusted.
3. Battery resistance too high for given regen
current.
4. Battery disconnected while regen braking.
