WARNING
After the power is turned on, the stroke limit function
does not work until the reference position return is
completed. During this period, the control unit
ignores the RT signal, if it is set to "1", and keeps
moving the tool at a feedrate selected by the manual
feedrate override signal. A parameter RPD (No.
1400#2) can be specified so that the rapid traverse
is validated before the reference position return is
completed.
Incremental feed amount selection signal DIST0-DIST26<G020-G023>
[Classification] Input signal
[Function] Selects a feed amount per incremental feed step. This signal is a 27-
point binary signal, and is related to a feed amount as follows:
Feed amount =
å
=
××
26
0
}2{
i
i
i
Vincrement input Least
where, Vi = 0 when DISTi is 0
Vi = 1 when DISTi is 1
A value from 0 to 99,999,999 can be selected. If a value that falls
outside this range is specified, 0 is assumed.
[Operation] Each time one step is fed by increment feed (with the feed axis
direction selection signal set to 1 after being set to 0), the tool is fed by
the feed amount specified by this signal.
NOTE
1 The least input increment is used for specification.
This means that the same specified value represents
a different feed amount, depending on whether
metric input or inch input is used. When a different
increment system is used for each axis, the same
specified value does not represent the same feed
amount.
2 With bit 3 (MPN) of parameter No. 2001, an
increment feed amount can be specified using
manual handle feed amount selection signals MP1,
MP2, and MP4, instead of specifying an arbitrary
value with this signal. See Section 3.2, "Manual
Handle Feed."
