Statement
●In this manual we have tried as much as possible to describe all the
various matters. However, we cannot describe all the matters which
must not be done, or which cannot be done, because there are so
many possibilities. Therefore, matters which are not especially
described as possible in this manual should be regarded as
“impossible”
Notice
●The product function and qualification (such as the accuracy, speed)
described in this manual is only for this product, which is installed the
CNC machine of this product. The actual function configuration and
technical capacity are determined by the setting of the manufacturer.
●The system is matched with the standard operation panel, but its
function of each key is defined by the PLC program (ladder diagram). It
is very important to note that the function of the key in this manual is
described for the standard PLC program!
●Refer to the manual issued by the manufacturer for the function of
each key on the operation panel and the meaning.
