CHAPTER EIGHT SPINDLE VELOCITY FUNCTION
8.1 Spindle Velocity Control Method
Brief
GSK218MC divides the spindle into gear spindle and analog spindle based upon the control
method.
1. In the gear spindle, the CNC controls the spindle speed by which the S code turns into
switch value and then outputs to the spindle.
2. In the analog spindle, the CNC controls the spindle speed by which the S code turns
into analog value and then outputs to the spindle.
The I/O point or analog value control can be set by bit 2 of bit parameter No.1.
8.1.1 Gear Spindle
Brief The gear spindle means that the spindle S code is controlled by I/O.

[Function]
These signals have been indicated that the specified spindle speed function
has been performed actually.
[Condition output]
Refer to the “S code miscellaneous function in Section 7.2 for
spindle S code I/O point control” for the output condition and
performance process.
Note:
S code range: S1
~
S8, the alarm may occur if it exceeds its range, S1
~
S8 are separately corresponding with
the F address signal F022#0~#7. User can refer to three gears (S1, S2 and S3) of the configured ladder
diagram from the system. So, S4~S8 can not be used, the corresponding ladder diagram should be added if
the user needs.
8.1.2 Analog Spindle
Brief
Analog spindle is that the spindle speed is controlled by the analog voltage value of the CNC.
CNC can be controlled the spindle speed of which the S code turns into the analog voltage
