Warning Status


This warning status alerts you that the protection function of the inverter has been activated. However, the
inverter keeps on running. If the inverter runs for a long time in this status, the inverter may enter the alarm
status and stop running.

In the status display mode, details of the warning and the status indication alternate on the display when a
warning has occurred. When the status display mode is not selected, the alternating display appears on the
display if the warning is still active after the status display mode is resumed.

All keys are valid during the warning status because the inverter continues to run.

Description
Acceleration (deceleration) time too short
Load too heavy, output frequency too high
Deceleration time too short
Load too heave, continuous operation will cause an inverter
shutdown.
Temperature of the radiator is rising. Check the ambient
temperature and operation of the cooling fan. The warning is issued
at a temperature 10℃ below the abnormal radiator fin temperature
(OH) (The abnormal radiator fin temperature differs depending
upon the output frequency, output current and other factors)
Brake resistor capacity too low. (%ED is small)
Brake resistor stops to prevent heat damage.
A feedback is abnormal. Please check feedback value and feedback
signal.
Since an operation command unallowed by the specified rotation
direction has been input, please confirm the setting of motor
rotation direction.
Two mounted optional boards are conflicting with each other.
(The optional board mounted on OPT2 will be invalid.)
For the same analog input channels, input current and voltage input
is set at the same time. Please confirm the function code selected
by analog input.
A reverse direction is detected by PG feedback. Please confirm the
phase of PG pulse.
