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 D75P2. When carrying
out other control ("main positioning control", "advanced positioning control", "zero
point return 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.
