Motor Temp Hot Cut-
back
Stop vehicle and allow to cool
down. If operating in a hot
environment, wait until
temperature cools down.
1. Motor temperature is at or above t he pr
ogramm ed Temperature Hot setting, and the
current is being cut back.
2. Motor Temperature Control Menu parameters
are mis- tuned.
3. See Monitor menu» Motor: Temperature
and » Inputs: Analog2.
4. If the application doesn’t use a motor ther-
mistor, Temp Compensation and Temp Cut-
back should be programmed Off.

Fault
Motor thermistor is not
connected properly or moter
temp sensor failure
1. Motor thermistor is not connected properly.
2. If the application doesn’t use a motor ther-
mistor, Motor Temp Sensor Enable should be
programmed Off.
3. See Monitor menu » Motor: Temperature
and » Inputs: Analog2.

Main contactor failure
1. Main contactor did not close.
2. Main contactor tips are oxidized, burned, or
not making good contact.
3. External load on capacitor bank (B+ connec-
tion terminal) that prevents capacitor bank
from charging.
4. Blown B+ fuse.
