4.3 Replacement Guidelines for Product
Parts
Electrical and electronic parts have a limited service life due to mechanical
wear and deterioration over time. Perform periodic inspections for preven-
tive maintenance.
Contact your Yaskawa representative for replacements based on the stan-
dard replacement periods that are given in the following table. Yaskawa will
inspect your product and determine if part replacement is required.
Yaskawa will initialize the settings of all parameters to the default values in
products that are returned for overhaul. Before you start operation again,
make sure that you reset the parameters that are required for operation.
