: Setting always required.
: Set according to requirements (Leave set to the initial value when not used.)
The "Parameters" must be set to carry out manual pulse generator operation.
The following table shows the setting items of the required parameters for carrying out
manual pulse generator operation. When only manual pulse generator 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.)
Setting item
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. But
Pr.24
(b8), is set only for axis 1. (The setting for axes 2,3, and 4 is ignored.)
•
Refer to CHAPTER 5 "DATA USED FOR POSITIONING CONTROL" for setting
details.
