Overvoltage Cutback
Reduced brake torque.
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.
5. See Monitor menu» Battery:
Capacitor Voltage
Set: Capacitor bank voltage
exceeded the Overvoltage limit
with FET bridge enabled.
Clear: Bring capacitor voltage
below the Overvoltage limit.

+5V Supply Failure
None, unless a fault action is
programmed in VCL.
1. External load impedance on
the +5V supply (pin 26) is too
low.
2. See Monitor menu» Outputs:
5 Volts and Ext Supply Current.
Set: +5V supply (pin 26) outside the
+5V ±10% range.
Clear: Bring voltage within range.

Digital Out 6 Overcurrent
Digital Output 6 driver will not turn
on.
1. External load impedance on
Digital Output 6 driver (pin 19) is
too low.
Set: Digital output 6 (pin 19)
current exceeded 15 mA.
Clear: Remedy the overcurrent
cause and use the VCL
function
Set_DigOut() to turn
the driver on again.
27
Digital Out 7 Overcurrent
Digital Output 7 driver will not turn
on.
1. External load impedance on
Digital Output 7 driver (pin 20)
is too low.
Set: Digital output 7 (pin 20)
current exceeded 15 mA.
Clear: Remedy the overcurrent
cause and use the VCL function
Set_DigOut() to turn the driver
on again.
