Axis mode

Why axis mode?
For certain machining tasks (e.g., on turning machines with end-face machining), the spindle
not only has to be rotated with M3, M4 and M5 and positioned with SPOS, M19 and SPOSA, but
also addressed as an axis with its own identifier (e.g., C).
Prerequisites
• The same spindle motor is used for spindle mode and axis mode.
• The same position measurement system or separate position measurement systems can
• A position actual-value encoder is a mandatory requirement for axis mode.
• If the axis is not synchronized, e.g., M70 is programmed after POWER ON, the axis must
