Machine data MD 14 defines the maximum operating speed of the main spindle motor. It acts
as the reference value of the speed setpoint interface.
Note:
The velocity of a main spindle is matched in NC-MD 4030 (maximum spindle speed). The
motor operating speed which corresponds to this maximum value must be entered in drive-MD
14. Allowance is made for any existing gear ratios in the relationship between NC-MD 4030
and drive-MD 14.
