5 DATA USED FOR POSITIONING CONTROL
The data is monitored with the PLC program or peripheral device. In this chapter,
the method using the peripheral device will be explained.

Monitor data
(Data that indicates the control state. Stored in the buffer memory, and monitors as necessary.)
System monitor data
Monitors the QD75MH specifications and the operation history.
Axis monitor data
Monitors the data related to the operating axis, such as the current position
and speed.

Control data
(Data for user to control positioning system.)
System control data
Writes/initializes the "setting data" in the module.

Control using the control data is carried out with the PLC program.
" Deceleration start flag valid" is valid for only the value at the time
when the PLC READY signal [Y0] turns from OFF to ON.

POINT
(1) The "setting data" is created for each axis.
(2) The "setting data" parameters have determined default values, and are set to
(2) The "setting data" parameters have determined default values, and are set to
the default values before shipment from the factory. (Parameters related to
axes that are not used are left at the default value.)
axes that are not used are left at the default value.)
(3) The "setting data" can be initialized with GX Configurator-QP or the PLC
program.
(4) It is recommended to set the "setting data" with GX Configurator-QP. When
executed with the PLC program, many PLC programs and devices must be
used. This will not only complicate the program, but will also increase the scan
time.
