TR/TL 25
(+5V) Supply Failure
External load impedance is too
low.
1. External load impedance on the +5V supply
(pin 26) is too low.
2. See Monitor menu >> outputs:
3. Volt s and E x t S upply Current.
TR/TL 26
Digital Out 6 Open/
Short
External load impedance is too
low.
1. External load impedance on Digital Output 6
driver (pin19) is too low.
TR/TL 27
Digital Out 7 Open/
Short Digital
External load impedance is too
low.
1. External load impedance on Digital Output 7
driver (pin20) is too low.
TR/TL 28
Motor Temp Hot Cut-
back
Stop vehicle and wait to cool
down. If operating in a hot envi-
ronment, wait until temperature
cools down.
1. Motor temperature is at or above the pro-
grammed 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.
TR/TL 29
Motor Temp Sensor
Fault
Motor thermistor is not connec-
ted properly or moter temp sen-
sor 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.
