(2) Operation in each control mode
- Spindle mode (ordinary spindle control)
The slave spindle rotates upon the issue of the same command as that used for
the master spindle.
The command does not specify the speed of the spindle, instead specifies the
ratio of the spindle motor speed to the maximum speed. So, if the spindle unit
configuration (maximum motor speed, motor-spindle gear ratio, and so forth) of
the master spindle is the same as that of the slave spindle, both spindles will
rotate at about the same speed. (The synchronization of rotation cannot be
guaranteed. If the configurations of the two spindles differ, the speed of one
spindle will differ from that of the other.)
- Cs contour control mode
When the Cs contour axis control option is selected, contour control can also be
applied to the slave spindle. Note, however, that independent control is not
possible, since the motion of the slave spindle is being controlled by the master
spindle. The display of the move command address and position data is limited
to the master spindle. Reference position return is also performed in the same
way as usual. However, both spindles are checked for the completion of
reference position return, so that the reference position return signal for the Cs
contour control axis is turned on only after reference position return has been
completed by both spindles.
While simple spindle synchronous control is applied, the user can switch
between spindle mode and Cs contour control mode.
(3) Parking function
In simple spindle synchronous control mode, the parking function stops the
motion of the master or slave spindle, regardless of the mode (spindle mode or
Cs contour control mode) of the spindle. In the parking state, the spindle is
placed in the following state, depending on its mode:
In spindle mode: Same state as when S0 is specified
In other modes: Zero distribution state
