HW0481994
• The inspection interval must be based on the servo power supply on time.
• For any different or special applications, the inspection process should be developed on
an case-by-case basis.
• For axes which are used very frequently (in handling applications, etc.), it is recom-
mended that inspections be conducted at shorter intervals. Contact your Yaskawa repre-
sentative.
