6.14.2Inverter 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).

6.14.3 External input trip stop

H

H

:External input trip stop mode selection

: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.
