B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 219 -
NOTE
The extended specification includes the following
two extensions:
(1) With the conventional specification, the number
of M codes for specifying a spindle positioning
angle is always 6. With the extended
specification, an arbitrary number of such M
codes from 1 to 255 can be selected by
parameter setting (See parameter No.4964.)
(2) The maximum feedrate for spindle positioning
(setting of parameter No.1420) can be
extended from 240000 to 269000 (in
increments of 10 deg/min).
IMB When the spindle positioning function is used, half-fixed angle
positioning based on M codes uses:
0 : Specification A
1 : Specification B
NOTE
In the case of half-fixed angle positioning based on
M codes, three types of spindle positioning
operations can occur:
(1) The spindle rotation mode is cleared, then the
mode is switched to the spindle positioning
mode.
(2) Spindle positioning is performed in the spindle
positioning mode.
(3) The spindle positioning mode is cleared, then
the mode is switched to the spindle rotation
mode.
In the case of specification A:
Operations (1) to (3) are specified using separate
M codes.
(1) Specified using M codes for performing spindle
orientation. (See parameter No.4960)
(2) Specified using M codes for specifying a
spindle positioning angle. (See parameter
No.4962)
(3) Specified using M codes for clearing spindle
positioning operation. (See parameter
No.4961.)
In the case of specification B:
When M codes for specifying a spindle positioning
angle are specified, operations
(1) to (3) are performed successively. (See
parameter No.4962.)
