10.6 Explanations of some signals
Spindle stop signal*SSTP (G29.6),
Spindles stop signal*SSTP1 (G27.3),*SSTP2 (G27.4)
● Signal Type: PLC → NC
● Signal Function: Break off the output of spindle speed instruction. The signal sets S instructions in
NC to 0, showing as the sequence chart below:
● Note: When spindle stop signal*SSTP is 0, output voltage turns to 0. When spindle stop signal*SSTP
is 1, analog voltage outputs instruction value. And if this signal is not used, keep setting
this signal to1, to make CN perform spindle speed control.

Spindle speed override signalSOV10
～
SOV13,SOV24
～
SOV27(G30)
● Signal Type: PLC → NC
● Signal Function: PLC assigns value to G30, and G30 transfers the value to NC. NC according to the value
of the G30 determines the different spindle speed override. SOV10
～
SOV13 are used for the 1
st
spindle,
while SOV24
～
SOV27 are used for the 2
nd
spindle.SOV10 ~ SOV13 coding and override values have a
relationship as follows:

spindle enabling signal ENB2 (F38.2)
● Signal Type: NC → PLC
● Signal Function: Indicate that whether spindle instruction exits.
