11.2.3 Setting the required parameters for JOG operation
The "Positioning parameters" must be set to carry out JOG operation.
The following table shows the setting items of the required parameters for carrying out
JOG operation. When only JOG operation will be carried out, no parameters other than
those shown below need to be set. (Use the initial values or setting values within a
range where no error occurs for trouble-free operation.)

REMARK
•
Positioning parameter settings work in common for all control using the QD75.
When carrying out other control ("major positioning control", "high-level positioning
control", "OPR positioning control"), the respective setting items must also be
matched and set.
•
Parameters are set for each axis.
•
Refer to "Chapter 5 Data Used for Positioning Control" for setting details.
