Output Phase Failure Detection; Emergency Stopping From The Operation Panel - Toshiba TOSVERT VF-nC3E Instruction Manual

2) Emergency stopping from the operation panel

Emergency stopping from the operation panel is possible
by pressing the STOP key on the panel twice while the inverter is not in the panel control mode.
(1) Press the STOP key ............................. "  " will blink.
(2) Press the STOP key once again ........... Operation will come to a trip stop in accordance with the setting
Note: While an emergency stop signal is input at a terminal, the trip cannot be reset. Clear the signal and
then reset the trip.

6.18.5 Output phase failure detection

f605 : Output phase failure detection selection
 Function
This parameter detects inverter output Phase failure. If the Phase failure status persists for one
second or more, the tripping function and the FL relay will be activated. At the same time, a trip
information epho will also be displayed.
Set f605 to 5 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.
f605 = 0 : No tripping (FL relay deactivated).
f605 = 1 : With the power on, the phase failure detection is enabled only at the start of the first operation.
The inverter will trip if the Phase failure status persists for one second or more.
f605 = 2 : The inverter checks for output phase failures each time it starts operation. The inverter will trip if
the Phase failure status persists for one second or more.
f605 = 5 : If it detects an all-phase failure, it will restart on completion of reconnection. The inverter does
not check for output phase failures when restarting after a momentary power failure.
Note1) A check for output phase failures is made during auto-tuning, regardless of the setting of this parameter.
