6 POSITIONING CONTROL
(10) Deceleration speed by the stop command (M3200+20n)/rapid stop command
(M3201+20n) is controlled with fixed inclination (deceleration speed).
Deceleration processing is executed using the speed limit value or deceleration/
rapid stop deceleration time set in the parameter block.

(11) When the fixed position stop command turns on, the command in-position check
starts. When the absolute value of difference between the setting address and
feed current value below the "command in-position range" set in the fixed
parameter, the command in-position signal (M2403+20n) turns on. The
command in-position signal (M2403+20n) turns on by a positioning start.
(12) In any of the following cases, positioning is executed at the speed that was
specified by the speed limit value.
• Speed control with fixed position stop is started with the fixed position stop
command turned ON.
• The fixed position stop command is turned ON after a speed change to "0".
