3) Selecting the operation of the FL relay
Using the output terminal selection parameter, you can specify whether or not to oper ate the FL relay.
H (output terminal selection 3) =  (default): Operates the FL relay in the event of an emergency stop.
H (output terminal selection 3) = : Does not operate the FL relay in the e vent of an emergency stop.

Note 1: Emergency stopping via the specified ter minal is possible, even during operation panel ope ration.
Note 2: If H= (Emergency DC braking) and DC b raking is not required for normal stopping, set the DC
braking time H to  [s].
4) Emergency stopping from the operation panel is possible
Pressing the STOP key on the operation panel twice enables emergency stop.
(1) Press the STOP key ———— “GQHH” will blink.
(2) Press the STOP key again — If H (Emergency stop) = ~, the motor makes an emergency stop (or
trips) according to the setting.
If “G” is displayed an error detection signal (FL) is issued (FL is activated).

H : Output phase failure detection mode selection
•
Function
This parameter detects inverter output phase failure. If the inverter detects an open phase failure, the
tripping function and the FL relay will be activated. At the same time, the trip information GRJQ will also
be displayed.
Detection errors may occur for special motors such as high-speed motors.
H=: No tripping
H=: With the power on, the phase failure detection is enab led only at the start of the first operation. The
inverter will trip if the inverter detects an open phase failure.
H=: The inverter checks for output phase failures each ti me it starts operation. The inverter will trip if the
inverter detects an open phase failure.
H=: The inverter checks for output phase failures during operation. The inverter will trip if the inverter
detects an open phase failure.
H=: The inverter checks for output phase failures at the start o f and during operation. The inverter will tr ip if
the inverter detects an open phase failure.
H=: If the inverter detects an open phase failure in every pha se, it does not trip but restarts operation when
every phase is reconnected.
The inverter does not check for output phase failures when restarting after a momentary power failure.
This function (H=) doesn't operate at 200V-55kW/75kw and 400V-90kW or more models.
Note: A check for output phase failures is made during auto-tuning 1 (H=, ), regardless of the setting of
this parameter H.
