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
Other functions
Follow up function
This function monitors the motor rotation amount with the servo
turned OFF, and reflects it on the current feed value.
12.8.2
Common functions
The outline of the functions executed as necessary are described below.
(Refer to "Section 2" for details on each function.)

Reference
section
Parameter initialization function
This function returns the "parameters" stored in the QD75
buffer memory and flash ROM to the default values.
The following two methods can be used.
1) Method using sequence program
2) Method using GX Configurator-QP
13.2
Execution data backup function
This functions stores the "setting data", currently being
executed, into the flash ROM.
1) Method using sequence program
2) Method using GX Configurator-QP
13.3
External I/O signal logic switching function
This function switches I/O signal logic according to externally
connected devices.
This function enables the use of the system that does not use b
(N.C.)-contact signals, such as Upper/lower limit signal, by
setting parameters to positive logic.
13.4
External I/O signal monitor function
This function monitors the external I/O signal monitor
information in the module's detailed information which can be
displayed on the system monitor of GX Developer 1.
13.5
1: Usable on GX Developer (SW6D5C-GPPW-E or later).
