6.14.2 Inverter trip retention
H : Inverter trip retention selection
• Function
This parameter is used to prevent the tripped inverter from being restored to working order
when the power is turned back on. The inverter can be restored by resetting it from the
operation panel (terminal).

★ Up to four sets of latest trip information displayed by the status monitor function can be stored
in memory.
★ When the power is turned back on, trip information (such as trip current and voltage) stored by
the status monitor function will be cleared.

6.14.3 External input trip stop
H : External input trip stop mode selection
H : DC braking time (s)
• Function
These parameters allow you to specify a method for stopping the inverter when it receives an
external trip stop signal via input terminals or an emergency stop signal from the operation
panel. When the inverter shuts down, the error message “G” is displayed on the inverter’s
display panel and the error FL relay (trip output) is activated. When H is set to 
(emergency DC braking), DC braking time also needs to be set using H.
1) External trip stop by means of a terminal
External trip stop can be performed by means of the a-terminal. Perform the following steps to
assign the external stop function to a terminal and to specify a stopping method.
