Replacement Guidelines for
Machine Controller Parts
Electrical and electronic parts have a limited service life due
to mechanical wear and deterioration over time. Perform peri-
odic inspections for preventive maintenance.
Contact your Yaskawa representative for replacements based
on the standard replacement periods that are given in the fol-
lowing table. Yaskawa will inspect your Machine Controller
and determine if part replacement is required.
Yaskawa will initialize the settings of all parameters to the
default values in Machine Controllers that are returned for
overhaul. Before you start operation again, make sure that you
reset the parameters that are required for operation.
