Data unit : Motor rotation for one rotation of spindle 100
(When parameter No. 4006 #1 (GRUNIT) is 1,
motor rotation 1000)
Data range : 0 to 32767
Standard setting : 100
These parameters set the gear ratio of the spindle motor relative to the
spindle.
When the motor rotates 2.5 time for every rotation of the spindle, for
example, set 250 in the parameter.
A parameter is selected by the CTH1A and CTH2A input signals.
The gear or clutch status must correspond to the status of the CTH1A and
CTH2A input signals.
