You will likely interact with or notice this parameter during specific maintenance scenarios:

Improperly setting this parameter can lead to inaccurate machining or damage.

For rotary tables (4th/5th axes), set 1860 in degrees per minute. A typical range: 1000–3000 deg/min. Because rotary inertia is lower than linear axes (usually), higher 1860 is acceptable, but watch for mechanical lash.

: It allows the machine to "remember" exactly where it is, even after power cycles, provided an absolute pulse coder (APC) is used.
