WARNING
Use the tap hole on the end of the shaft only to prevent the tool from
dislocating.
Do not use only this hole to install the tool. The tool could dislocate and
fly off the installation section during robot operation.
When the ZS or ZRS unit is attached to the 3rd or 4th-axis, install the tool onto
the ZS or ZRS shaft in the following manner. (The ZS and ZRS shaft have the
same shape.)
Use the 
φ12 section on the shaft, and fix the tool with a bolt coupling or split clamp.
