B-63950EN/02 4.DESCRIPTION OF PARAMETERS
- 219 -
NOTE
When a serial spindle is used, this parameter is
invalid for the specification of a rotation direction for
the orientation command.
# 6 ESIs The unit of rapid traverse rate on the spindle positioning axis is:
0: Not increased by a factor of 10.
1: Increased by a factor of 10.
# 7 IMBs When the spindle positioning function is used, half-fixed angle
positioning based on M codes uses:
0: Specification A
1: Specification B
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. (After switching to the spindle
positioning mode, spindle orientation operation is also
performed.)
(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 an M code for switching to the spindle
positioning mode.
(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.) (However, spindle orientation operation of
(1) is not performed.)
