5.7.8
Emergency drive (Fire mode)
This function is used in case of emergency such as a fire to forcibly continue inverter operation to drive
a motor without activating protective functions even if the inverter detects a fault. Using this function
may cause damage of the motor or the inverter because driving the motor is given the highest pri-
ority. Use this function for emergency operation only.
When the inverter is damaged by a fault, the motor operation can be continued by switching to the
commercial power supply operation.
The emergency drive function is available only for the standard model.
The setting is available only for standard models.
Set Pr. 524 after setting Pr. 523.
When Pr. 523 = "100, 200, 300, 400", the emergency drive is activated regardless of the Pr. 524
setting.
