<Relation of spindle limit rotation speed and spindle maximum rotation speed>
The spindle rotation speed which can be attained at the spindle motor's maximum rotation speed is
set for the limit rotation speed (slimt). This value is obtained by multiplying the gear ratio on the
spindle motor maximum rotation speed (SP017). Set the maximum rotation speed (smax) when
the rotation speed is to be limited according to the machine specifications, such as the spindle gear
specifications. Up to four value can be set for gear changeover.
SP017
<Relation of tap time constant and actual acceleration/deceleration time constant>
(For constant inclination synchronous tap cycle)
Set the acceleration time up to the tap rotation speed (stap) in the tap time constant (stapt).
Acceleration/deceleration is carried out at the same inclination for all speed commands. Up to four
values can be set for gear changeover.
