Definition
The inverter output current rose to or above about
200% of the rated inverter current during
acceleration.
The inverter output current rose to or above about
200% of the rated inverter current during constant-
speed operation.
The inverter output current rose to or above about
200% of the rated inverter current during
deceleration or stop.
Excessive regenerative energy or surge voltage
occurred during acceleration.
Excessive regenerative energy or surge voltage
occurred during constant speed.
Excessive regenerative energy or surge voltage
occurred during deceleration or stop.
Overload or reduced cooling capability during low-
speed operation Protection from burning due to
motor temperature rise.
Current more than 150% of the rated output current
flew and overcurrent shut-off did not occur. Output
transistor protection from overheat.
Temperature rise of the heat sink.
Ground fault occurred on the inverter's output side.
External thermal relay provided for protection from
overheat was actuated (contact open).
Error occurred in the parameter stored.
Operation could not be resumed properly within the
pre-set number of retries.
Arithmetic operation of the built-in CPU does not end
within the predetermined time.
