the unnecessary or unallowable operations because there are too
many possibilities. Therefore, the matters not specially described
herein should be considered as “impossible” or “unallowable”.
Warning！
zBefore installing, connecting, programming and operating the product,
please read this manual and the manual provided by the machine tool
builder carefully, and operate the product according to these manuals.
Otherwise, the operation may cause damage to the product and
machine tool, or even cause personal injury.
Caution！
zThe functions and specifications (e.g., precision and speed) described
in this manual are only for this product itself. For those CNC machine
tools installing this product, the actual function configuration and
specifications depend on the designs of the machine tool builders.
Moreover, the function configuration and specifications of the CNC
machine tool are subject to the manual provided by the machine tool
builder.
