Important: The formats in this table indicate the maximum number of digits left and maximum number of digits right of
the decimal point for each word. In many cases they are not valid together since the control allows a maximum of 8 total
digits. Refer to the system installer’s manual for specific formats.
The maximum programmable value accepted by the control is 99,999,999.
The minimum is .000001 inch or .00001 mm. However, the actual range
of programmable values depends on specifications determined by the
system installer.
By using AMP to establish the format of numeric values for words, the
system installer sets the “programming resolution,” for axis motion, that is,
the smallest programmable distance of axis motion.
