Does M311 apply to both turning spindles?

No — M311 is only for turning spindle No. 2 (the second turning spindle on the twin-spindle INTEGREX e-670H-S).

Turning Spindle No. 2 C-Axis Braking

Q: What does Mazak M-code M311 do?

M311 — Turning Spindle No. 2 C-Axis Braking on the MAZATROL SmoothX control (INTEGREX e-670H). This function code activates the C-axis braking mechanism to brake the C-axis when the turning spindle No. 2 is connected to the C-axis. During high-speed positioning that requires high accuracy or during machining with EIA programs, apply the low-pressure brake as necessary using the relevant M codes.

Machine-specific. This M-code list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). M-code assignments differ between Mazak models, control generations and PLC configurations — verify against the manual for your own machine before relying on any code.

Twin-spindle note (*1): M311 applies only to turning spindle No. 2 — the second turning spindle on the e-670H-S.
