Cs contour control mode
The Cs contour control change signal is used to switch between
spindle rotation control (method of controlling the rotation of the
spindle with the velocity command) and spindle contour control
(method of controlling the rotation of the spindle with the move
command). The mode for spindle contour control is called the Cs
contour control mode. The manual and automatic operation of the
spindle in the Cs contour control mode can be performed as with
normal servo axes.
Although interpolation is enabled for the spindle and servo axis in the
Cs contour control mode, this subsection describes only spindle
positioning, not interpolation of the spindle and servo axis.
Setting the Cs contour control axis
The axis targeted for Cs contour control is placed as one axis of CNC
control axes. Any of the control axes can be selected as the Cs contour
control axis, but one of -1, -2, -3, and -4 ("-n" indicates that the n-th
spindle is used as the Cs axis) must be set for specifying the servo axis
number (parameter No. 1023).
The Cs contour control axis must be set as a rotation axis (bit 0
(ROTx) of parameter No. 1006 is 1 and parameter No. 1022 is 0).
The axis name (parameter No. 1020) of the Cs contour control axis
can be arbitrarily selected.
When the second to fourth spindles are selected as Cs axes, bit 7
(CSS) of parameter No. 3704 must be set to 1.
Shifting to Cs contour control
To shift from the spindle rotation control mode to the Cs contour
control mode, set the Cs contour control change signal CON to 1. This
immediately stops the spindle and then executes mode switching.
Shifting to spindle rotation control
To shift from the Cs contour control mode to the spindle rotation
control mode, set the Cs contour control change signal CON to 0.
Before switching, make sure that the move command for the spindle
during automatic or manual operation is fully completed. If the
switching is made while the spindle is rotating, the interlock state is
entered or an alarm indicating a too large positional deviation occurs.
