13. Alarm list
•Check the power supply voltage
•Check the wiring of the power
supply cable
•The power supply voltage
be-camelower than approximately
60% of the rated voltage
•The power supply voltage
exceeded approximately 120% of
the rated voltage.
•Vertical drive(gravitational
operation) was performed or a
load exceeding the permissible
load inertia was driven.
•The temperature inside drive
exceeded the alarm detection
temperature.
•Excessive current has flown
through the drive due to ground
fault. Etc.
•Actual speed and set speed are
different.
•The motor sensor signal line
experienced an open circuit during
operation or the motor signal
connector came off.
•The rotation speed of the motor
output shaft exceeded
approximately 4800rpm
•A load exceeding the continuous
duty region was applied to the motor
for the time exceeded the value set
in the “The overload alarm detection
time” parameter.
•When the power is turned on
with the operation switch set to
the "RUN" side.
•When the power is turned on
while the FWD input or REV input is
set to “ON”.
•The motor instantaneous stop
when EXT-ERROR(Stop) input.
•Check the power supply voltage
•If this alarm occurs during
operation, reduce the load or
make the acceleration/deceleration
time longer.
•Review the ambient temperature.
•Check the wiring between the
drive and motor for damage.
•Check the power supply voltage.
•Check the load.
•Check the wiring between the
drive and motor.
•Reduce the load
•Review the operation pattern
such as acceleration/deceleration
time.
•Set the operation switch to the
“STAND-BY”
•Turn the FWD input or REV input
from ON to OFF.
•.Check the EXT-ERROR input..
Change status from activated to
deactivated
