shows the relationships with other parameters.
When positioning is started,
the acceleration starts following
the "acceleration time".
1) Positioning start
2) Sudden stop cause occurrence
When a "sudden stop cause" occurs,
the deceleration starts following the
"sudden stop deceleration time".
3) Positioning stop
When a "sudden stop cause"
does not occur, the decelera-
tion starts toward the stop
position following the "decel-
eration time".

Stop group 3 sudden stop selection
Set the method to stop when the stop causes in the following stop groups occur.
Stop group 1 ............. Stop with hardware stroke limit
Stop group 2 ............. Error occurrence of the PLC CPU, PLC READY signal
[Y0] OFF, Fault in test mode
Stop group 3 ............. Axis stop signal from PLC CPU
Stop signal from test function of GX Works2
Error occurrence (excludes errors in stop groups 1 and 2:
includes only the software stroke limit errors during JOG
operation, speed control, speed-position switching control,
and position-speed switching control)
The methods of stopping include "0: Normal deceleration stop" and "1: Sudden
stop".
If "1: Sudden stop" is selected, the axis will suddenly decelerate to a stop when the
stop cause occurs.
