Monitor Data; Control Data - Mitsubishi Electric QD77MS User Manual

Monitor data

The data indicates the control status. The data is stored in the buffer memory.
Monitor the data as necessary.
The monitor data is classified as follows.
Monitor data
System monitor data
Axis monitor data
Synchronous control monitor data
Mark detection 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.

Control data

The data is used by users to control the positioning system.
The control data is classified as follows.
Control data
System control data
Axis control data
Synchronous control data
Mart detection 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.
Chapter 5 Data Used for Positioning Control
Monitors the specifications and the operation history
of Simple Motion module.
Monitors the data related to the operating axis, such
as the current position and speed.
Monitors the data for synchronous control.
Monitors the data for mark detection.
Writes/initializes the "positioning data" in the module.
Sets the setting for operation of all axes.
Makes settings related to the operation, and controls the speed change
during operation, and stops/restarts the operation for each axis.
Sets the data for synchronous control.
Sets the data for mark detection control.
