When checking for conduction with multimeter, connect the battery pack to “BAT” and “OBT” of encoder con-
nectors on the motor, and then remove the encoder connector for each axis from motor. Otherwise, the
home position may be lost. (Refer to " 9.3.7 Notes for Maintenance ".)
*2
Internal cables are to be replaced at 24000 H inspection.
*3
For the grease, refer to "Table 8 Inspection Parts and Grease Used".
*4
Inspection numbers correspond to the numbers in "Fig. 19 Inspection Parts and Inspection Numbers (Manip-
ulator in the Home Position)".
*5
The occurrence of a grease leakage indicates the possibility that grease has seeped into the motor; this can
cause a motor breakdown. Contact your Yaskawa representative.
The numbers in the above table correspond to the numbers in "Table 7 Inspection Items".
