9 MAJOR POSITIONING CONTROL

9.2 Setting the positioning data

9.2.1 Relation between each control and positioning data

MELSEC-Q

The setting requirements and details for the setting items of the positioning data to be

set differ according to the "

Da.2

Control system".

The following table shows the positioning data setting items corresponding to the different types of control. Details and settings for the operation of each control are shown in Section 9.2.2 and subsequent sections.

(In this section, it is assumed that the positioning data setting is carried out using GX Configurator-QP.)

: Always set		: Set as required ("–" when not set)

: Setting not possible (If setting is made, an error (error code: 516) will occur at a start.)

–: Setting not required (Setting value is invalid. Use the initial values or setting values within a range where no error occurs.) : The "ABS (absolute) system" or "INC (incremental) system" can be used for the control system.
