Chapter 5 Data Used for Positioning Control
Monitor data (Data that indicates the control state. Stored in the buffer memory, and monitors as necessary.)
Monitors the QD77MS specifications and the operation history.
Monitors the data for synchronous control.
System monitor data
Synchronous control data
Monitors the data related to the operating axis, such as the current position
and speed.
Axis monitor data
The following methods are available for data monitoring:
• Set using GX Works2.
• Create the sequence program for monitoring using GX Works2 and execute it.
In this manual, the method using the GX Works2 will be explained.
Makes settings related to the operation, and controls the speed change
during operation, and stops/restarts the operation for each axis.
Axis control data
(Data for user to control positioning system.) Control data
Output signals (Axis stop signal, JOG start signal and execution
prohibition flag) from PLC CPU to QD77MS.
Expansion axis control data
Writes/initializes the "setting data" in the module.
Sets the setting for operation of all axes.
System control data
Sets the data for synchronous control. Synchronous control data
Control using the control data is carried out with the sequence program.
"
Cd.41
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
the default values before shipment from the factory. (Parameters related to
axes that are not used are left at the default value.)
(3) The "setting data" can be initialized with GX Works2 or the sequence program.
(4) It is recommended to set the "setting data" with GX Works2. The sequence
program for data setting is complicated and many devices must be used. This
will increase the scan time.
