11.2.3 Setting the required parameters for JOG operation

The "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

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.
