Output Phase Failure Detection - Toshiba TOSVERT VF-MB1 Instruction Manual

Setting example) When assigning the emergency stop function to S2 terminal
Title
f114 Input terminal selection 4A (S1)
Setting value 21 is reverse signal.
Note 1) Emergency stopping via the specified terminal is possible, even during panel operation.
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 ............................." eoff " 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.

6.24.5 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. (Failure signal FL not activated)
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. (Failure signal FL
activated)
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. (Failure signal FL activated)
f605 = 3 : The inverter checks for output phase failures during operation. The inverter will trip if the Phase
failure status persists for one second or more. (Failure signal FL activated)
f605 = 4 : The inverter checks for output phase failures at the start of and during operation. The inverter will
trip if the Phase failure status persists for one second or more. (Failure signal FL activated)
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. (Failure
signal FL not activated)
Function
0 - 203
of the f603 parameter.
After this, " e " will be displayed and a failure detection signal
generated (FL relay is activated).
