Spindle Clamp Speed Setting; G92 - Mitsubishi Electric MELDAS C6 Programming Manual

10. Spindle Functions

10.6 Spindle clamp speed setting; G92

Function and purpose
The maximum clamp speed of the spindle can be assigned by address S following G92 and the
minimum clamp speed by address Q.
Command format
G92 Ss Qq;
Ss
Qq
Detailed description
(1) Besides this command, parameters can be used to set the rotational speed range up to 4
stages in 1 r/min units to accommodate gear selection between the spindle and spindle motor.
The lowest upper limit and highest lower limit are valid among the rotational speed ranges
based on the parameters and based on G92 Ss Qq ;
(2) Set in the parameters "#1146 Sclamp" and "#1227 aux11/bit5" whether to carry out rotation
speed clamp only in the constant surface speed mode or even when the constant surface
speed is canceled.
