If the fuse is blown, replace it with the same type of fuse (supplied).The supplied parts of YASNAC XRC is as follows. Parts No.1 to 3 are used for fuse for replacement and No.4 is used as a tool for connecting the I/O.
Recommended Spare Parts
It is recommended that the following parts and components be kept in stock as spare parts for the XRC. The spare parts list for the XRC is shown below. Product performance can not be guaranteed when using spare parts from any company other than Yaskawa. To buy the spare parts which are ranked B or C, inform the manufacturing number (or order number ) of XRC to Yaskawa representative. The spare parts are ranked as follows: • Rank A: Expendable and frequently replaced parts • Rank B: Parts for which replacement may be necessary as a result of frequent operation • Rank C: Drive unit
