Emergency Stop; Overload Reduction Start-Up Frequency; Motor's 150%-Overload Time Limit - Toshiba TOSVERT VF-P7 Instruction Manual

6.25.4 Emergency stop

 ：Emergency stop
 ：Emergency DC injection braking control time
・Function
Emergency stop mode of can be selected. At emergency stop, a trip message ("") is displayed.
Note) When setting  at  or (Emergency DC injection braking stop), you need to set also the
parameters (DC injection braking current) and (Emergency DC injection braking
control time).
1) Emergency stop by terminal operation
Emergency stop can be performed with the a or b-contact. Assign the emergency stop function
to a terminal as described below, and select a stop mode.

Note 1) An emergency stop can be carried out from the terminal even in panel operation mode. In this case,
however, holding down the Stop key for more than 5 seconds causes the inverter trip ()
even when  is set at ,  or .
Note 2) If DC injection braking is not needed for normal stops, though  is set at  or  (emergency
DC injection braking), then set the DC braking time  at   [s].
2) Emergency stop by panel operation
Emergency stop can be performed with the control panel, in other operation command mode.
Press twice the STOP key on the control panel.
