(d) Signal for integral speed control (INTGA)
[Function] Enables or disables integral speed control.
[Operation] When this signal is set to 1, integral speed control is disabled. (Same
effect as when the integral gain of the velocity loop is set to 0.) When the
signal is set to 0, integral speed control is enabled.
When the two spindles are mechanically connected with each other, this
signal is set to 1 for both spindles so that integral speed control is
disabled.
D When a cylindrical workpiece is held with the two spindles after they
are synchronized in speed
D When a workpiece with a unique shape is held with the two spindles
after they are synchronized in phase

(b) Signal indicating that synchronization control of spindle speed is completed (FSPSY)
[Function] Reports that synchronization control of spindle speed is completed.
[Output conditions] This signal is set to 1 when the following conditions are satisfied:
D In spindle synchronization control mode, the two spindles reach the
speed specified by the signal for specifying the spindle speed in
synchronization, and the difference between the speeds of the two
spindles is not more than the value specified in parameter 4033(FS16).
This signal is set to 0 when any of the following conditions is satisfied:
D In spindle synchronization control mode, the two spindles have not yet
reached the speed specified by the signal for specifying spindle speed
in synchronization.
D In spindle synchronization control mode, the difference between the
speeds of the two spindle is larger than the value specified in parameter
4033 (FS16).
D The spindles are not in spindle synchronization control mode.
NOTE
The signal changes from 1 to 0 when the difference in
spindle speed exceeds the value specified in parameter
4033(FS16) due to changes in the cutting load, etc.
