N o te
If a value is entered both for DP and for DPR, the final drilling depth is derived from DPR. If this differs from the absolute
depth programmed via DP, the message "Depth: Corresponding to value for relative depth" is output in the dialog line.
If the values for reference and retraction planes are identical, a relative depth specification is not permitted. The error
message 61101 "Reference plane defined incorrectly" is output and the cycle is not executed. This error message is also
output if the retraction plane is located after the reference plane, i.e. its distance to the final drilling depth is smaller.
Programming example: Drilling_centering
This program produces three drill holes using the CYCLE81 drilling cycle. The drilling axis is always the Z axis.
