Output Phase Failure Detection - Toshiba TOSVERT VF-nC1 Instruction Manual

(An example of terminal assignment) Assigning the trip stop function to the R terminal
Title
Notes:
1) Emergency stop by means of the specified terminal is possible, even when operation is
controlled from the operation panel.
2) If (DC braking starting frequency) is set to 0.0 (Hz) and
time to 0.0 (sec), the DC braking function will not be activated even if
(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 _________ "
Press the STOP key again ____ Operation will be stopped in accordance with the setting of

Output phase failure detection

: 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
Set 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.
