8 CONTROL SUB FUNCTIONS
8.1 Outline of Sub Functions
*1 The near pass function is validated only when the machine of the standard specification carries out the position control with the
continuous path control mode. It cannot be invalidated with parameters.
Functions related to
positioning stop Stop command processing
for deceleration stop
function This function selects a deceleration curve when a stop cause occurs during deceleration stop
processing to speed 0.
Continuous operation
interrupt function This function interrupts continuous operation. When this request is accepted, the operation stops
when the execution of the current positioning data is completed.
Step function This function temporarily stops the operation to confirm the positioning operation during debugging,
etc.
The operation can be stopped at each "automatic deceleration" or "positioning data".
Other functions Skip function This function stops the positioning being executed (decelerates to a stop) when the skip signal is
input, and carries out the next positioning.
M code output function This function issues a sub work (clamp or drill stop, tool change, etc.) according to the code No. (0 to
65535) set for each positioning data.
The M code output timing can be set for each positioning data.
Teaching function This function stores the address positioned with manual control into the positioning address ([Da.6]
Positioning address/movement amount) having the designated positioning data No.
Command in-position
function This function calculates the remaining distance for the Simple Motion module to reach the positioning
stop position, and when the value is less than the set value, sets the "command in-position flag".
When using another sub work before ending the control, use this function as a trigger for the sub
work.
Acceleration/deceleration
processing function
This function adjusts the control acceleration/deceleration.
Deceleration start flag
function
This function turns ON the flag when the constant speed status or acceleration status switches to the
deceleration status during position control, whose operation pattern is "Positioning complete", to
make the stop timing known.
Follow up function This function monitors the motor rotation amount with the servo turned OFF, and reflects it on the
current feed value.
Speed control 10

multiplier setting for
degree axis function
This function executes the positioning control by the 10

speed of the command speed and the
speed limit value when the setting unit is "degree".
Operation setting for
incompletion of home
position return function
This function is provided to select whether positioning control is operated or not when the home
position return request flag is ON.
