Setting the required parameters for manual pulse generator
operation
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 always required,
: Set according to requirements
*1
*1
Leave it set to the initial value when not used.
Remark
●
Parameter settings work in common for all control using the LD75. 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.22] Manual pulse generator input logic (b8), [Pr.24] is set only for axis 1. (The
setting for axes 2, 3, and 4 is ignored.)
