Monitor data (Data that indicates the control state. Stored in the buffer memory, and monitors as necessary.)
System monitor data
Axis monitor data
Synchronous control data
Mark detection monitor data
Control data (Data for user to control positioning system.)
System control data
Axis control data
Expansion axis control data

(1) The "setting data" is created for each axis.
(2) The "setting data" parameters have determined default values, and are set to
(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
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.
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.
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.
Output signals (Axis stop signal, JOG start signal and execution
prohibition flag) from PLC CPU to Simple Motion module.
Sets the data for synchronous control.
Sets the data for mark detection.
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.
