TOMATECH AUTOMATION
Command format：M5n；(n=0～8)
Command function：M50：cancel orientation state;
M5n(n=0～8)：the spindle oriented to No. n point.
Note: Refer to time sequence and logic of M50～M58 defined by standard PLC ladder in Ⅲ
INSTALLATION & CONNECTION.
The 2nd spindle rotation CCW, rotation CW , stop M63, M64, M65
Command format: M63；
M64；Ⅰ Programming
M65；
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 thisTAC-1002T 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,TAC-1002T 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 ofTAC-1002T
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.
