• The following methods are available for data setting. In this manual, the method using the engineering tool will be
explained. (Refer to the next "Point".)
• Set using the engineering tool.
• Create the program for data setting using the engineering tool and execute it.
• The basic parameters 1, detailed parameters 1, home position return parameters, "[Pr.83] Speed control 10  multiplier
setting for degree axis", "[Pr.89] Manual pulse generator/Incremental synchronous encoder input type selection", "[Pr.90]
Operation setting for speed-torque control mode" and "[Pr.95] External command signal selection" become valid when the
PLC READY signal [Y0] turns from OFF to ON.
• The basic parameters 2, detailed parameters 2 (Note that this excludes "[Pr.83] Speed control 10  multiplier setting for
degree axis", "[Pr.90] Operation setting for speed-torque control mode", "[Pr.95] External command signal selection",
"[Pr.122] Manual pulse generator speed limit mode" and "[Pr.123] Manual pulse generator speed limit value".) become valid
immediately when they are written to the buffer memory, regardless of the state of the PLC READY signal [Y0].
• Even when the PLC READY signal [Y0] is ON, the values or contents of the following can be changed: basic parameters 2,
detailed parameters 2, positioning data, and block start data.
• The servo parameter is transmitted from the Simple Motion module to the servo amplifier when the initialized
communication carried out after the power supply is turned ON or the CPU module is reset. The power supply is turned ON
or the CPU module is reset after writing servo parameter in flash ROM of Simple Motion module if the servo parameter is
transmitted to the servo amplifier.
• The only valid data assigned to basic parameter 2, detailed parameter 2, positioning data or block start data are the data
read at the moment when a positioning or JOG operation is started. Once the operation has started, any modification to the
data is ignored. Exceptionally, however, modifications to the following are valid even when they are made during a
positioning operation: acceleration time 0 to 3, deceleration time 0 to 3, and external command function.
Setting data that can be
changed during operation
Acceleration time 0 to 3, deceleration
time 0 to 3
External command function selection
• The "setting data" is created for each axis.
• 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.)
• The "setting data" can be initialized with the engineering tool or the program.
• It is recommended to set the "setting data" with the engineering tool. The program for data setting is
complicated and many devices must be used. This will increase the scan time.
Monitor data
The data indicates the control status. The data is stored in the buffer memory. Monitor the data as necessary.
The setting data is classified as follows.
Item
System monitor data
Axis monitor data
Servo network composition status
Synchronous control data
• The following methods are available for data monitoring:
• Set using the engineering tool.
• Create the program for monitoring using the engineering tool and execute it.
• In this manual, the method using the engineering tool will be explained.
12 DATA USED FOR POSITIONING CONTROL
362
12.1 Types of Data
Details
Positioning data are pre-read and pre-analyzed. Modifications to the data four or more steps after the current step are
valid.
The value at the time of detection is valid.
Description
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 related to the current network state.
Monitors the data for synchronous control.
