3 SPECIFICATIONS AND FUNCTIONS

Sub function

Details

Reference

section

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".

12.7.1

Skip function

This function stops (decelerates to a stop) the positioning being
executed when the skip signal is input, and carries out the next
positioning.

12.7.2

M code output function

This function issues a command for a sub work (clamp or drill
stop, tool change, etc.) corresponding to the M code No.
(0 to 65535) that can be set for each positioning data.

12.7.3

Teaching function

This function stores the address positioned with manual control
into the positioning address having the designated positioning

data No. (

Cd.39

).

12.7.4

Target position change
function

This function changes the target position during positioning.
Position and speed can be changed simultaneously.

12.7.5

Command in-position
function

At each automatic deceleration, this function calculates the
remaining distance for the QD75 to reach the positioning stop
position. When the value is less than the set value, the
"command in-position flag" is set to "1".
When using another auxiliary work before ending the control,
use this function as a trigger for the sub work.

12.7.6

Acceleration/deceleration
process function

This function adjusts the control acceleration/deceleration.

12.7.7

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.

6.5.4

Pre-reading start function

This function shortens the virtual start time.

12.7.8

Deceleration start flag
function

Function that 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.

12.7.9

Other functions

Stop command processing
for deceleration stop
function

Function that selects a deceleration curve when a stop cause
occurs during deceleration stop processing to speed 0.

12.7.10
