Emergency Stop - Toshiba TOSVERT VF-AS1 Instruction Manual

6.33.3 Emergency stop

 : Emergency stop
 : Emergency DC braking control time
• Function
Emergency stop mode can be selected. At emergency stop, a trip message ("") is displayed. FL relay can
be deactivated using the output function selection.
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.
2) Emergency stop
=: The motor is brought to a stop within the time specified with 
=: DC braking is performed at the current specified with  (DC braking current) for the time
=: The motor is brought to a stop within the time specified with  (deceleration time 4).

3) Selecting the operation of the FL relay
Using the output terminal selection parameter, you can specify whether or not to operate the FL relay.
 (output terminal selection 3) =  (default): Operates the FL relay in the event of an emergency stop.
 (output terminal selection 3) = : Does not operate the FL relay in the event of an emergency stop.

Note 1: Emergency stopping via the specified terminal is possible, even during operation panel operation.
Note 2: If = (Emergency DC braking) and DC braking is not required for normal stopping, set the DC
braking time  to  [s].
4) Emergency stopping from the operation panel is possible
Pressing the STOP key on the operation panel twice enables emergency stop.
(1) Press the STOP key ———— "" will blink.
(2) Press the STOP key again — If  (Emergency stop) = ~, the motor makes an emergency stop (or
