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
specified with (emergency DC braking control time).
Use this setting to bring the motor to a stop within time different from the normal deceleration time specified with
.
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.

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].
