Forced operation (Fire Mode) (Operation selection)
(Confirmation time)
(Set frequency)
(Run direction)
(Starting method)
(Waiting time)
Set when wishing to enable forced operation (Fire Mode). With forced operation, the motor can be forcibly run at
the specified speed. Even if an alarm occurs during forced operation, operation can be continued. If an alarm occurs
due to a protective function such as OC (instantaneous overcurrent protection), operation is resumed with automatic
reset. The time until operation is resumed can be set. If switching to forced operation, “Fod” is recorded in the alarm
history for the purpose of retaining a record. If continuing operation with forced operation, alarms that are
automatically reset are not recorded in the alarm history.
By assigning “FMS” to a digital input terminal and turning “FMS” ON, forced operation (Fire Mode) is enabled.
(Function code E01 to E09, data = 134)
By assigning “FMRUN” to a digital output terminal, it turns ON during forced operation. (Function code E20 to E24,
E27, data = 95)
By selecting automatic reset with forced operation, the inverter will continue to run with no protective
functions, resulting in a risk of inverter damage or fire, etc.
