Spindle Speed Function
8.1 Spindle Speed Control Mode
General
For GSK980TC3 system, the spindle is divided into gear spindle and analog spindle:
1. In gear spindle mode, CNC changes S code to switch value to output to the spindle to
control the spindle speed.
2. During analog spindle, changes S code to analog value to output to the spindle to
control the spindle speed.
The control mode is I / O or analog is set by bit parameter NO:1#2.
8.1.1 Gear Spindle
General
The gear spindle is defined that the spindle S code is controlled by I/O point.

corresponding ladder must be added.
8.1.2
Analog Spindle
General
The analog spindle is defined that the spindle speed is controlled by the analog voltage
value from the CNC. The CNC changes S code into the analog voltage value to output to
the spindle of machine tool to control the spindle speed.
The actual output analog voltage value equals to the S value controlled by the spindle
multiplying the spindle override.

Spindle override code detection signal has 3 binary system code signals which
are corresponding with the override:
So, the spindle override can be selected based upon the 10% unit within the
50~120%.
When the spindle speed control is performed instead of using the spindle speed
override, the setting override value is 100%.
Note: The spindle speed override function is invalid in thread cutting.
Gear change process:
Although S instructs the spindle speed, the actual is to control the spindle motor. So, the
CNC needs to confirm the corresponding relation between the spindle motor and gear. Like S
