are deleted.

Programmable adjustable parameters

The following parameters should be programmed in the main program for "Measure
kinematics" with CYCLE996:
_CHBIT[25]
● 0 = Only enter calculated offset vectors when the operator has acknowledged M0 with NC
● 1 = Enter calculated offset vectors immediately (no M0)
_CHBIT[26]
● 0 = Measurement with the calibration ball parallel to the axis
● 1 = Measurement with the calibration ball at an angle

Start.
– For Calculate kinematics and measurement variant "Enter measuring result".
– Only when the tolerance of the offset vectors has not been exceeded in the
calculation.
With this variant, the kinematics can be measured, e.g. at 90 degree positions, without
the shank of the calibration ball mechanically preventing the measurement.
The starting angle, parameter _STA1, must be specified externally in the main program.
Value range of the starting angle _STA1, 0 to 360 degrees.
The leading angle _INCA is equal to 90 degrees.
Parameter _SPEED[1] is used as feedrate on the circular path.
