Set when enabling forced operation (Fire Mode). In an emergency, operation at a specified
speed can be performed. Even when an alarm of the inverter is generated, operation is
continued. In such a case where instant overcurrent protection occurs, the retry function is to
be used to restart the operation.
Assigning the FMS to a digital input terminal and turning the FMS ON enables forced
operation (Fire Mode). (Function code E01 to E07; data = 134)
When the inverter is running with the FMS being ON, the protective function is
disabled. Therefore, the inverter keeps running even if an alarm occurs so that the
inverter could be broken or a fire could occur.
