12.3 RESET ROTARY COORDINATE
SYSTEM
(Cycle 801, DIN/ISO: G801)
Please note while programming:
The Cycle 801 RESET ROTARY COORDINATE
SYSTEM is machine-dependent. Refer to your
machine manual.
With Cycle 801 RESET ROTARY COORDINATE
SYSTEM you can reset the settings you have made
with Cycle 800 ADAPT ROTARY COORDINATE
SYSTEM.
Cycle 800 limits the maximum spindle speed during
eccentric turning. Therefore, program Cycle 801 to
reset Cycle 800, and reset the speed limitation with
FUNCTION TURNDATA SPIN SMAX.
Effect
Cycle 801 resets the following settings you have programmed with
Cycle 800:
Precession angle Q497
Reverse tool Q498
If you have executed the eccentric turning function with Cycle 800,
the cycle limits the maximum spindle speed. To reset this, program
FUNCTION TURNDATA SPIN SMAX in addition to Cycle 801.
Cycle 801 does not orient the tool to the starting
position. If a tool was oriented with Cycle 800, it
remains in this position also after resetting.
Cycle parameters
Cycle 801 does not have a cycle parameter. Finish
the cycle input with the "END" key.
