Command function:
M63: spindle rotation CCW;
M64: spindle rotation CW;
M65: spindle stop.
Note 1: The sequence of M63, M64, M65 defined by the standard PLC is the same that of M03, M04, M05.
Note 2: The function is enabled when the 2nd spindle function is valid.
2.2 Spindle Function
S command is used for controlling spindle speed and this GSK980TDc has two modes to control
it:
Spindle speed switching value control: S □□ (2 digits command value)is executed by PLC, and
PLC outputs switching value signal to machine tool to change spindle speed with grades.
Spindle speed analog voltage control: S □□□□ (4 digits command value)specifies actual speed of
spindle and NC outputs 0~10V analog voltage signal to spindle servo or converter to realize stepless
spindle speed.
2.2.1 Spindle speed switching value control
Spindle speed is controlled by switching value when No.001 BIT4 is set to 0. There is only one S
command in a block, otherwise the system alarms.
Their executing sequence is defined by PLC when S command and word for moving function are
in the same block. Please refer to
User Manual
from machine manufacturer.
When spindle speed is controlled by switching value, GSK980TDc Turning CNC system is used
for machine tool and the time sequence and logic of executing S command is according to
User
Manual
from machine manufacturer. Refer to S command defined by standard PLC of GSK980TDc
as follows:
Command format: S □□
00
～
04(the leading zero can be omitted): No.1
～
No.4 gear of spindle
speed is controlled by switching value.
In spindle speed switching value control mode, after S signal transmits to PLC, the system dwells
time defined by No.081, then return FIN signal, and the dwell time is called runtime of S command.
S01, S02, S03, S04 output are reserved when resetting CNC.
S1
～
S4 output are invalid when CNC is switched on. The corresponding S signal output is valid
and reserved, and others are cancelled at the same time when executing one of S01, S02, S03, S04.
When executing S00, S1
～
S4 output are cancelled and only one of S1
～
S4 is valid at the same time.
2.2.2 Spindle speed analog voltage control
Spindle speed is controlled by analog voltage when No.001 BIT4 is set to 1.
Command format: S □□□□
