f404 emergency braking time 0~20.0 s 1.0
0: Coast stop
1: Slowdown stop
2: Emergency DC braking
These parameters allow you to specify how to stop operation using an external control
device when an external trip occurs. When operation stopped, the trip e-43 displayed.
When setting f403 =2 (emergency DC braking), set also f507 (DC braking rate) and f404
(emergency braking time). Assigning the trip stop function (input terminal function 11 or
27) to the contact input terminal.
Note 1: Emergency stopping via the specified terminal is possible, even during panel
operation.
Note 2: If DC braking is not needed to bring the motor to a stop under normal conditions,
although f403 is set to 2 (emergency DC braking), set the DC braking starting frequency
(f506) at 0.0 Hz.
NO. Parameter Name Setting Range
Default
f405 Input phase failure detection 0~1 0
0: Disabled, No tripping.
1: Enabled, Phase failure detection is enabled during operation.
This parameter detects inverter input Phase failure. If the abnormal voltage status of
main circuit capacitor persists for few minutes or more, the tripping function will be
activated.
Therefore, input phase failures cannot always be detected. A trip information e-41 will be
displayed. If the power capacity is larger than the inverter capacity (more than 200kVA or
more than 10 times), detection errors may occur. If this actually happens, install an AC or
DC reactor.

Output phase failure detection mode

0~5 0
0: Disabled.
1: At start-up (Only one time after power is turned on).
2: At start-up (each time).
