7.2.7 Linear servo motor/DD motor setting parameters ([Pr. PL_ _ ])
POINT
The linear servo motor/DD motor setting parameters ([Pr. PL_ _ ]) can be used
with the direct drive servo system for the indexer method.
Linear servo motor/DD motor setting parameters ([Pr. PL_ _ ]) cannot be used
with MR-J4-03A6-RJ servo amplifiers.
