Troubleshooting and Fault information
Fault
Name
E008
Fault Descriptions
1.The AC drive detects
excessive drive output
current.
2.The AC drive can withstand
up to 150% of the rated
current for a maximum of 60
seconds.
E009
The over-current hardware
trip circuit detects an
abnormal increase in current.
Corrective Actions
Check whether the motor is overloaded.
Reduce the torque compensation setting as set
in F1-54.
Increase the AC drive's output capacity.
Check whether the motor output power
corresponds to the AC drive output power.
Check the wiring connections between the AC
drive and motor for possible short circuits.
Increase the Acceleration time 1 and 2 (F1-10,12).
Check for possible excessive loading conditions
at the motor.
After short-circuit being removed, if there is any
abnormal conditions when operating the AC
Motor Drive, it should be sent back to the
agency or manufacturer.
E00A
The AC drive detects that the
DC bus voltage has exceeded
its maximum allowable value.
Check whether the input voltage falls within the
rated AC drive input voltage. Check for
possible voltage transients.
Bus over-voltage may also be caused by motor
regeneration. Either increase the Decel time or
add an optional braking resistor. Check whether
the required braking power is within the
specified limits.
The external terminal EF-DCM
E00d goes from ON to OFF.
External fault.
E00E
The AC drive temperature
sensor detects excessive
heat.
E00F
AC drive E2PROM contains
invalid data or can not be
programmed.
Ensure that the ambient temperature falls
within the specified temperature range.
Make sure that the ventilation holes are not
obstructed.
Remove any foreign objects on the heatsinks
and check for possible dirty heatsink fins.
Provide enough spacing for adequate
ventilation.
Check the connections between the main
control board and the power board.
Reset drive to factory defaults.
