FAULT NAME
CODE
0X25 Ext 5V Supply Failure
0X26 Ext 12V Supply Failure
0X28 Motor Temp Hot Cutback
0X29 Motor Temp Sensor
0X31 Main Driver
POSSIBLE CAUSES
1. External load impedance on the
+5 V supply (pin 16) is too low.
2. See Programmer » System
Monitor menu » Outputs:
External_5V_Supply,
Ext_5V_Current.
1. External load impedance on the
+12 V supply (pin 23) is too low.
2. See Programmer » System
Monitor menu » Outputs:
External_12V_Supply,
Ext_12V_Current.
1. Motor temperature is at or above
the programmed Temperature Hot
setting—resulting in a reduction of
controller drive current.
2. The motor temperature and
sensor control parameters are
misadjusted.
3. See Programmer » AC Motor
Setup
» Temperature Sensor.
1. Motor thermistor is not connected
properly.
2. sensor polarity (between Pin 9
and Pin 12) is incorrect.
3. The motor temperature and
sensor parameters are misadjusted.
4. See Programmer » System
Monitor menu » AC Motor »
Temperature.
1. Open or short on driver load.
2. Dirty connector pins at controller
or contactor coil.
3. Bad connector crimps or faulty
wiring.

SET/CLEAR CONDITIONS
Set: (1) The 5 V Supply (pin
16) is outside 5 V±10 % (2)
The current is outside limits
defined by:
Ext_5V_Supply_Min
Ext_5V_Supply_Max
Clear: Reset Controller, or
Re-set using VCL variable
Ext_5V_Output_Enable
Set: (1) The 12 V supply (pin
23) is outside 12 V ± 15 % (2)
The current is outside the
limits defined by:
Ext_12V_Supply_Min
Ext_12V_Supply_Max
Clear: Reset Controller. Or
Re-set using VCL variable
Ext_12V_Output_Enable.
Set: Motor temperature is at
or above the Temperature Hot
parameter setting.
Clear: Bring the motor
temperature within range.
Set: Motor thermistor input
(pin
9) is at the voltage rail.
Clear: Bring the motor ther-
mistor input voltage within
range.
Set: Main Contactor driver is
either open or shorted. This
fault can be set only when
Main Enable = On.
Clear: Restore/repair any
external wiring or device-coil
to their correct state, then
Reset Controller.
