Coefficient for polygonal machining spindle acceleration

Q: What does Mazak parameter SU20 do?

SU20 is a User parameter in the SYSTEM group of the MAZATROL SmoothX control (INTEGREX e-670H). Coefficient for polygonal machining spindle acceleration. During polygonal machining, acceleration of the turning and milling spindle can be decreased by this parameter. Spindle acceleration for polygonal machining = Note : This value will be handled as100 if a negative value, 0 or a value more than 100 is set here. If during polygonal machining alarm 43 SPINDLE MALFUNCTION 2 (52, , ) occurs for the milling spindle, set a value less than 100 in this parameter to elongate the turning spindle speed attainment time (acceleration is decreased).

Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.

What it does

During polygonal machining, acceleration of the turning and milling spindle can be decreased by this parameter. Spindle acceleration for polygonal machining = Note : This value will be handled as100 if a negative value, 0 or a value more than 100 is set here. <Supplementary description> If during polygonal machining alarm 43 SPINDLE MALFUNCTION 2 (52, , ) occurs for the milling spindle, set a value less than 100 in this parameter to elongate the turning spindle speed attainment time (acceleration is decreased).
