4) Emergency stopping from the operation panel is possible
Pressing the STOP key on the operation panel twice enables emergency stop.

6.26.4 Output phase failure detection

: 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
be displayed.
Detection errors may occur for special motors such as high-speed motors.
= : No tripping
= : With the power on, the phase failure detection is enabled only at the start of the first operation. The
inverter will trip if the inverter detects an open phase failure.
= : The inverter checks for output phase failures each time it starts operation. The inverter will trip if the
inverter detects an open phase failure.
= : The inverter checks for output phase failures during operation. The inverter will trip if the inverter
detects an open phase failure.
= : The inverter checks for output phase failures at the start of and during operation. The inverter will trip if
the inverter detects an open phase failure.
= : If the inverter detects an open phase failure in every phase, 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.
