4. DESCRIPTION OF PARAMETERS
203
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 specifiection 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.)
4960
M code specifying the spindle orientation
[Data type] Word
[Unit of data] Integer
[Valid data range] 6 to 97
Set an M code to change the spindle rotating mode to the spindle
positioning mode. Setting the M code performs the spindle orientation.
Spindle positioning can be specified from the next block.
4961
M code releasing the spindle positioning mode
[Data type] Word
[Unit of data] Integer
[Valid data range] 6 to 97
Set the M code to release the spindle positioning mode and to change the
mode to the spindle rotating mode.
4962
M code for specifying a spindle positioning angle
[Data type] Word
[Unit of data] Integer
[Valid data range] 6 to 92
Two methods are availablel for specifying spindle positioning. One
method uses address C for arbitrary–angle positioning. The other use an
M code for half–fixed angle positioning. This parameter sets an M code
for the latter method.
