(Status8,5)
Severe KSI Overvoltage
ShutdownMotor;
ShutdownMainContactor;
ShutdownEMBrake;
ShutdownThrottle;
FullBrake.
1. See Monitor menu » Battery:
Keyswitch Voltage.
2. Incorrect low power circuit
voltage applied.
3. Low power circuit voltage spike caused
by inductive load switching, etc.
Set: KSI voltage exceeded 20 V.
Clear: Bring KSI voltage below 20 V, and then
cycle KSI.
19
(Status9, bit3)
PMAC Commissioning Needed
Hold all three phases at 50%
PWM and disables main weld
and DNC faults.
The PMAC Commissioning Procedure
has not yet been performed to set up the
controller for a new PMAC motor.
Set: PMAC Commissioning Needed parameter
set to 1.
Clear: PMAC Commissioning Needed parameter
set to 0.
22
(Status2,6)
Controller Overtemp Cutback
Reduced drive and brake torque.
1. See Monitor menu »
Controller: Temperature.
2. Controller is performance-limited at
this temperature.
3. Controller is operating in an
extreme environment.
4. Excessive load on vehicle.
5. Improper mounting of controller.
Set: Heatsink temperature exceeded 85°C.
Clear: Bring heatsink temperature below 85°C.
23
(Status2,3)
B+ Undervoltage Cutback
Reduced drive torque.
1. Normal operation. Fault indicates the
batteries need recharging. Controller is
performance limited at this voltage.
2. Battery parameters are misadjusted.
3. Non-controller system drain on battery.
4. Battery resistance too high.
5. Battery disconnected while driving.
6. See Monitor menu » Battery:
Capacitor Voltage.
7. Blown B+ fuse or main contactor did
not close.
Set: Capacitor bank voltage dropped below the
Undervoltage limit (see pages 27 and 69) with
the FET bridge enabled.
Clear: Bring capacitor voltage above the
Undervoltage limit.
24
(Status2,4)
B+ Overvoltage Cutback
Reduced brake torque. Note: This
fault is declared only when the
controller is running in regen.
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 (see pages 27 and 69) with the
FET bridge enabled.
Clear: Bring capacitor voltage below the
Overvoltage limit.
25
(Status5,3)
+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
5 V±10% range.
Clear: Bring voltage within range.
26
(Status4,1)
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
1 Amp.
Clear: Remedy the overcurrent cause and use
the VCL function Set_DigOut() to turn the driver
on again.
