Toshiba VF-nC1 instruction manual Emergency stop by means of the operation panel

E6581090

(An example of terminal assignment) Assigning the trip stop function to the R terminal

Title	Function	Adjustment range	Default setting
H	Input terminal selection 2 (R)	0~40, 49, 54~57	11
			(External trip stop)
Notes:

1)Emergency stop by means of the specified terminal is possible, even when operation is controlled from the operation panel.

2)If H (DC braking starting frequency) is set to 0.0 (Hz) and H (DC braking time to 0.0 (sec), the DC braking function will not be activated even if H is set to 2 (emergency DC braking).

2)Emergency stop by means of the operation panel

	The emergency stop function can be controlled from the operation panel when the RUN and STOP
	keys on the panel are not in use for operation (when they are inoperative).
	To activate the emergency stop function, press the STOP key on the operation panel twice.
	①Press the STOP key _________ “GQHH” will blink.
	Press the STOP key again____ Operation will be stopped in accordance with the setting of
	H. At the same time, “G” will be displayed and a	6
	failure detection signal (FL) will be put out (FL activated).
6.14.4	Output phase failure detection

H : Output phase failure detection mode selection

• Function

This parameter allows you to select a mode of detecting an output open-phase failure. If an open-phase failure persists for one second or more, the tripping function and the FL relay will be activated, and at the same time, the error message GRJQ will be displayed.

Set H to “” to open the motor-inverter connection by switching commercial power operation to inverter operation. Detection errors may occur for special motors such as high-speed motors.

H＝ (Disabled)･･･････････････ No tripping (FL relay not activated)

H＝ (Enabled) ･･･････････････ An open-phase check is performed when operation is started for the first time after power has been turned on. The inverter will trip if an open-phase failure persists for one second or more. (FL relay activated)

H＝ (Enabled) ･･･････････････ An open-phase check is performed each time operation is started. The inverter will trip if an open-phase failure persists for one second or more. (FL relay activated)

Title	Function	Adjustment range	Default setting
		0: Disabled
	Output open-phase	1: Enabled (Checked at the first
H	failure detection mode	start of operation)	0
	selection	2: Enabled (Checked at each start
		of operation)

6.14.5Motor 150%-overload time limit

H : Motor 150%-overload time limit

• Function

This parameter is used to set the time elapsed before the inverter trips when the motor is operated under a load of 150%.

Title	Function	Adjustment range	Default setting
H	Motor 150%-overload time	10～800 (sec)	300
