8-3 Warning Status
8-3 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.
8-3-1 List of warnings
table 8-3 List of warnings
Warning display Warning content Description
Current limiting during acceleration
/ deceleration
Acceleration (deceleration) time too short
Current limiting during constant
speed operation
Load too heavy, output frequency too high
During overvoltage prevention Deceleration time too short
Overload warning
Load too heave, continuous operation will cause an inverter
shutdown.
Radiator temperature warning 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)
Overheating of brake resistor
Brake resistor capacity too low. (%ED is small)
Brake resistor stops to prevent heat damage.
Disconnection of feedback cable
I.e. feedback circuit abnormality. Please check feedback value and
feedback signal.
Disallowance of the motor rotation
direction Since an operation command unallowed by the specified rotation
direction has been input, please confirm the setting of motor
rotation direction.
Option error Two mounted optional boards are conflicting with each other.
(The optional board mounted on OPT2 will be invalid.)
Conflict warning for analog input
setting Set voltage input and current input for same analog input channels.
Please confirm the function code selected by analog input.
PG line error detection A reverse direction is detected by PG feedback. Please confirm the
phase of PG pulse.
