Clearing Latched Faults
A latched fault is cleared only after the fault has been corrected and at least one of the following
actions has been taken:
•
Power-cycle the +24 Vdc to the drive
•
Cycle (disable and then enable) an enable input that is configured as
Enables with Clear Faults or Enables with Reset
•
Access the CME Control Panel and press Clear Faults or Reset
•
Clear the fault over the CANopen network or serial bus
Example: Non-Latched vs. Latched Faults
For example, the drive temperature reaches the fault temperature level and the drive reports the
fault and disables the PWM output. Then, the drive temperature is brought back into operating range.
If the Drive Over Temperature fault is not latched, the fault is automatically cleared and the drive's
PWM outputs are enabled. If the fault is latched, the fault remains active and the drive's PWM
outputs remain disabled until the faults are specifically cleared (as described above).

Fault Occurs When...
Drive's internal temperature exceeds
specified temperature.
Encoder-based phase angle does not
agree with Hall switch states. This fault can
occur only with brushless motors set up
using sinusoidal commutation. It does not
occur with resolver feedback or with Halls
correction turned off.
Over current condition detected on the
output of the internal +5 Vdc supply used to
power the feedback. Resolver or analog
encoder not connected or levels out of
tolerance.
Motor over-temperature switch changes
state to indicate an over-temperature
condition.
Bus voltage falls below specified voltage
limit.
Bus voltage exceeds specified voltage limit.
User set following error threshold
exceeded.
Output to output, output to ground, internal
PWM bridge fault.
2
Output current I T limit has been exceeded.

Fault is Corrected When...
Power module temperature falls below
specified temperature.
Encoder-based phase angle agrees
with Hall switch states.
Encoder power returns to specified
voltage range.
Feedback signals stay within specified
levels.
Temperature switch changes back to
normal operating state.
+ DC bus voltage returns to specified
voltage range.
+ DC bus voltage returns to specified
voltage range.
