MAINTENANCE AND TROUBLESHOOTING
14
Drive Over Power
Fault
Drive current and voltage
output, in combination
with the heatsink tem-
perature indicate that the
power output required by
the drive would damage
the power section.
Verify ambient temperature is
not too high.
Operate within the continuous
power rating.
Reduce acceleration rates.
Check for mechanical load prob-
lems and adjust as necessary.
Resize the application and apply
components accordingly.
15
Motor Tempera-
ture Fault
Motor thermostat trips due
to high motor ambient
temperature
Operate within (not above) the
continuous torque rating for the
ambient temperature (40°C
maximum).
Lower ambient temperature, in-
crease motor cooling.
Check that motor is properly
sized for the application. If nec-
essary, resize the motor.
Motor thermostat trips due
to excessive current
Reduce acceleration rates.
Increase time permitted for mo-
tion.
Use larger drive and motor.
Reduce duty cycle (ON/OFF) of
commanded motion.
Check tuning.
Motor thermostat trips due
to motor wiring error.
Check motor wiring.
Motor thermostat trips due
to incorrect motor selec-
tion.
Verify the proper motor has been
selected.
16
Continuous Cur-
rent Fault
Current exceeds the con-
tinuous motor current rat-
ing for an extended period
of time.
Change motor and or drive to be
compatible with load require-
ments.
Check tuning.
17
Drive Heatsink
Temperature Fault
Drive heatsink tempera-
ture exceeds drive heat-
sink fault limit
Let the drive cool down and/or
reduce the load.
22
Drive F1 Feedback
Fault
Error is detected in the
motor feedback
Verify motor selection is correct.
Check to be sure the correct en-
coder is attached.
Verify encoder wiring is correct.
Use shielded cables with twisted
pair wires.
Route the encoder feedback ca-
ble away from potential noise
sources.
Check ground connections.
