Chapter 5 Data Used For Positioning; Types Of Data - Mitsubishi Electric MELSEC Q Series User Manual

CHAPTER 5
This chapter describes parameters and data used for positioning.
5.1

Types of Data

The parameters and data required to carry out control with the QD73A1 include "setting data", "monitor data", and
"control data" shown below.
Setting data
Parameters
( Pr.1 to Pr.13 )
Positioning data
( Da.1 to Da.5 )
● The data can be set using GX Works2.
● Default values are determined for setting data parameters, and are set as the factory default. Keep the unused
parameters to the default.
● Fixed parameters and OPR parameters are activated when PLC READY signal (Y2D) is turned on.
● Variable parameters and positioning data can be changed even when PLC READY signal (Y2D) is on. Although, the
change that is made during operation is not reflected since the data set at the start of major positioning control or JOG
operation are valid. The change will be reflected at the next start.
Monitor data
(Data that indicates the control status. The data can be monitored when necessary.)
Monitoring area
( Md.1 to Md.22 )
DATA USED FOR POSITIONING
(Data to be set beforehand according to the machinery and application)
Positioning
Fixed parameters
parameters
( Pr.1 to Pr.9 )
Note
Variable parameters
Note
OPR
OPR parameters
parameters
( Pr.10 to Pr.13 )
Positioning data
Monitor data such as a current position, error codes, and error history.

CHAPTER 5 DATA USED FOR POSITIONING

Set parameters that are fixed beforehand
depending on the mechanical system.
If a setting of fixed parameters is outside the setting range,
default values will be set to all of the fixed parameters
for the control.
Set parameters that vary depending on
each positioning control.
If a setting of variable parameters is outside the setting range,
a default value will be set to only the corresponding parameter
for the control.
Set data for OPR.
Set start data for major positioning control.
