Corrective Action
Increase the deceleration time setting (F02).
Correct the AC line input voltage.
Replace with an appropriately rated drive.
Correct the AC line input voltage.
Replace with an appropriately rated drive.
Replace with an appropriately rated drive.
Improve ventilation to reduce ambient temperature.
Press the

Factor
y set.
Stop the drive and then change the function
range or code.
Set F06 frequency setting higher than F07.
Probable Cause
Deceleration time is set too low
.
AC line input voltage too high.
Inertial load too great.
AC line voltage is too low or incorrect drive
voltage rating.
Load current exceeds drive rating.
Ambient temperature is too high.
When the external stop signal is activated using
the multifunction input terminal, the motor will
decelerate and stop. The display will flash “E.S.”
after the motor stops.
When the external stop signal is activated using
the multifunction input terminal, the drive will
cease operation.
Attempt to reverse motor direction when F22 = 001.
Attempt to program F22= 001 when F04 = 001.
Pressing the
▲
or
▼
/RESET key when F11 = 001 or
Preset Speed operation is selected.
Attempt to change F29 setting (CPU V
ersion).
Attempt to change a function that cannot be
changed while the drive is running.
F06 and F07 frequency setting are the same.
