IOR
[Data type] Bit
IOR Resetting the system in the spindle positioning mode
0 : Does not releases the mode.
1 : Releases the mode
IDM The positioning direction for the spindle using a M code is
0 : The positive direction
1 : The negative direction
ISZ When an M code for spindle orientation is specified in spindle
positioning:
0 : The spindle rotation mode is cleared and the mode is switched to the
spindle positioning mode, and spindle orientation operation is
performed.
1 : The spindle rotation mode is cleared and the mode is switched to the
spindle positioning mode but spindle orientation operation is not
performed.
TRV Rotation direction of spindle positioning is set to:
0 : The positive direction
1 : The reverse direction
ESI Selection of a spindle positioning specification
0 : The conventional specificaion is used.
1 : The extended specificaion is used.
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 256 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
