N0120 %
Note 1: S value commanded in G96 is also reserved in G97. Its value is resumed when the system
is in G96 again;
Example:
G96 S50; (Cutting surface speed 50m/min)
G97 S1000; (Spindle speed 1000 r/min)
G96 X3000; (Cutting surface speed 50m/min)
Note 2: The constant surface speed control is valid when the machine tool is locked (X, Z do not
move when their motion command are executed);
Note 3: To gain the precise thread machining, it should not be adopted with the constant surface
speed control but the constant rotational speed (G97) in the course of thread cutting;
Note 4: From G96 to G97, if none of S command (r/min) is commanded in the program block in
G97, the last spindle speed in G96 is taken as S command in G97, namely, the spindle
speed is not changed at this time;
Note 5: In G96, when the spindle speed counted by the cutting surface speed is more than max.
speed of current spindle gear (system parameter No.037～No.040), at this time, the spindle
speed is limited to max. one of current spindle gear.
2.2.4 Spindle override
When the spindle speed analog voltage control is valid, the spindle actual speed can be
tuned real time by the spindle override and is limited by max spindle speed of current gear
after the spindle override is tuned, and it also limited by limited values of max. and min.
spindle speed in constant surface speed control mode.
The system supplies 8 steps for spindle override (50%～120% increment of 10%). The
actual steps and tune of spindle override are defined by PLC ladder and introductions
from machine manufacturer should be referred when using it. Refer to the following
functions ofTAC-1002T standard PLC ladder.
The spindle actual speed specified byTAC-1002T standard PLC ladder can be tuned real
time by the spindle override tune key at 8 steps in 50%～120% and it is not reserved when
the spindle override is switched off. Refer to the operations of spindle override in Ⅱ
OPERATION.
2.2.5 Multiple spindle control function
TAC-100XT can control up to two analog spindles. One S code is used to command one
of them which are selected by PLC signal and which have the gear change function.
BecauseTAC-1002T has only one spindle encoder interface, the 2nd spindle has no
encoder feedback and the spindle speed is not displayed.
Being the speed command, S code is sent to the spindle selected by the spindle selection
signal（SWS1, SWS2 <G27＃0, G27＃1>）, and each spindle rotates with the specified
speed. When the spindle has not received the spindle selection signal, it rotates with the
previous speed, which makes the spindle rotates with different speed in different time.
Each spindle has its own stop signal and enabling signal.
When №001＃4 is set to 1, setting MSEN（№196＃4）to 1 can start the multiple spindle
