6 POSITIONING CONTROL
(3) Stop commands and stop processing
The stop commands and stop processing for speed control are shown in the
table.6.1.
Table.6.1 Stop commands and stop processing
Stop command Stop condition Stop axis Stop processing
STOP signal input of the
Q172LX (STOP)
Deceleration stop based on the parameter
block or the "deceleration time on STOP
input" specified with the servo instruction.
Stop command
(M3200+20n)
Deceleration stop based on the parameter
block or the "deceleration time" specified with
the servo instruction.
Rapid stop command
(Note)
(M3201+20n)
OFF
ON
Specified
axis
Deceleration stop based on the parameter
block or the "rapid stop deceleration time"
specified with the servo instruction.
Rapid stop of the all axes/
deceleration stop from the
peripheral devices.
(Note)
(Test mode)
Click icon All axes
Deceleration stop based on the parameter
block or the "rapid stop deceleration time"
specified with the servo instruction.

axis
Deceleration stop based on the parameter
block or the "deceleration time" specified with
the servo instruction.
POINT
(Note): The rapid stop command and the rapid stop of the all axes from the
peripheral devices are also valid during deceleration by the "STOP signal
input of the Q172LX" (STOP) or stop command (M3200+20n), and
processing based on the "rapid stop deceleration time" parameter starts at
the time the stop condition occurs.

[Cautions]
(1) After executing of the speed control using the absolute position system, the feed
current value cannot be set to "0" by the following operations:
• Reset
• Turning the servo power supply on (OFF
ON)
(2) The dwell time cannot be set.
