Data description
9.2 Cycle data
For tool measurement with CYCLE971 only
_CM[ ]
Monitoring functions for tool measurement with rotating spindle, only active if _CBIT[12]=0
Changes valid after value assignment
Data type REAL
Significance: CYCLE971: _CM[0]..._CM[7]
Monitoring functions for tool measurement with rotating spindle, only active if
_CBIT[12]=0
_CM[0]
_CM[1]
_CM[2]
_CM[3]
_CM[4]
_CM[5]
_CM[6]
_CM[7]
CYCLE982: _CM[8], only active if _CBIT[7]=1
Tolerance parameter for tool measurement with orientational tool carrier - 90°
multiples of the tool positions
Under some circumstances, the actual angular position of the axes can
deviate from the programmed value; it is for this reason that this tolerance
variable has been introduced.
_CM[8]
For tool measurement with CYCLE971 only
_MFS[ ]
Feeds and speeds for tool measurement with rotating spindle, only active if _CBIT[12]=1
Changes valid after value assignment
Data type REAL
