9. SPINDLE SPEED FUNCTION
337
low gear range, the gear select signal does not change and the command
output is calculated and output to obtain the set speed at high gear.
When the spindle motor speed is set by parameter GST (No. 3705#1)=1,
the command output is output regardless of gear select signal. When the
spindle motor speed is set, it is used for gear shift.

[Classification] Input signal
[Function] This signal keeps the spindle motor at a constant rotation speed, if a gear
shift occurs when spindle orientation is in progress.
[Operation] When spindle orientation is in progress, setting the gear shift signal to 1
causes a constant command output to be generated regardless of the gear
position, if the rotation speed of the spindle motor has been specified. The
signal can be used for gear shifting if the spindle motor rotation speed has
been specified. The signal implements a function equivalent to that of the
GST parameter (bit 1 of parameter No. 3705). It is valid if GST is 0.
