6.15.4 External input trip stop mode selection

: External input trip stop mode selection : Emergency DC braking time

• Function

These parameters set the method of stopping the inverter in external trip stop mode. When the inverter is stopped, the trip detection function (" " display) and the FL relay are activated. If

is set to " " (Emergency DC braking), also set	(DC braking current) and
(Emergency DC braking time).

1) External trip stop via terminals

The external trip stop function can be executed via the a-contact. Proceed as follows to assign an external stopping terminal and select the stopping method:

	Input terminal
6	CC

a-contact

[Parameter setting]

Title	Function	Adjustment range		Default setting

	External input trip stop mode selection	0: Coast stop		0
	External input trip stop mode selection	1: Slowdown stop		0
		2: Emergency DC braking
	Emergency DC braking time	0.0 ∼ 20.0 (s)		1.0
	DC braking current	0∼ 100 (%)		30

(Example of terminal assignment): Assigning the trip stop function to the RST terminal
Title	Function	Adjustment range		Setting

	Input terminal selection (RST)	0 ∼ 51	11
	Input terminal selection (RST)	0 ∼ 51	(External trip stop)
			(External trip stop)
Notes:

1)Emergency stopping via the specified terminal is possible, even during panel operation.

2)If is set to "2" (Emergency DC braking) and DC braking is not required for normal stopping, set

the DC braking time ( ) to 0.0 (sec).
