Stop Functions
12.1 Type of Stop Functions
12.1.1 Type of Stop Functions
• The following seven stop operations are available.
• The system stop, emergency stop, deceleration stop, and pause will be effective when
allocated request signals turn on by user programs.
• The limit stop, software limit stop, and error stop will be effective when corresponding
conditions are established.

Occurrence condition and operation
Once a system stop request (Y0) turns on, the
operations of all active axes will stop.
Stops in the deceleration time of 1 ms.
Once a limit + input and limit - input turns on,
an active operation will stop and the operation of
corresponding axes will stop. "Limit switch"
under "Axis parameter settings" > "Basic setup"
should be set to "A: Enabled".
Performs a deceleration stop in the "limit stop
deceleration time" specified in the axis
parameter.
When the software limit function is effective,
an active operation will stop and the
corresponding axes will stop when it exceeds
the range of the software limit.
Performs a deceleration stop in the "error stop
deceleration time" specified in the axis
parameter.
When a unit error occurs, the operation of
corresponding axes (all axes or axis in which the
error occurs) will stop.
Target axes vary depending on the selection
of the parameter "MC common settings" >
"Operation when an error occurs".
Performs a deceleration stop in the "error stop
deceleration time" specified in the axis
parameter.
When an emergency stop request
(corresponding bit allocated to UM001B0 to
UM001B5) turns on an active operation will stop
and the operation of corresponding axes will
stop.
Performs a deceleration stop in the
"emergency stop deceleration time" specified in
the axis parameter.
