TOMATECH AUTOMATION
1 7 5 SAR
Bit6 1: The spindle SAR signal is checked before cutting;
0: The spindle SAR signal is not checked before cutting.
Data parameter
0 7 2 SAR_DELEY
Delay check time (ms) of the spindle speed arrival.
D T 0 5 MTIME
Execution time of M code (ms)
D T 1 0 SPDDLT
Spindle braking delay output time after spindle stop (M05) is output
D T 1 1 SPZDTIME
Spindle braking output time (ms)
340
Ⅲ Connection
D T 2 3 SVF_DELEY
Delay time before spindle motor torque decrease to 0 when spindle starts clamping;
D C 0 0 SPZERO
Spindle zero speed output range (m/min);
� Signal connection
M03, M04, M05, SPZD signal output circuit is shown in Fig. 2-45A:
Fig. 2-45A
SAR, SALM signal input circuit is shown in Fig.2-45B:
Fig.2-45B
� Operation sequence （defined by standard PLC program）
Spindle operation sequence is show in Fig 2-46:
Fig. 2-46 spindle rotation(CW/CCW) sequence
Note: T2 is the delay time from sending the spindle stop signal to sending the spindle brake
signal; T3 is the
spindle brake hold time.
� Function description（defined by standard PLC program）
① After the CNC is turned on, when M05 output is valid, M03 or M04 is executed, M03 or
M04
output is valid and remains, at the time, M05 output is closed; when M03 or M04 output is
valid, M05
is executed, M03 or M04 is closed, M05 output is valid and remains; the spindle brake
SPZD signal
output delay is set by No.087（delay time from the spindle stop signal output to the spindle
brake
SPZD signal output）, the hold time of the brake signal is set by No. 089（the spindle brake
output
time）.
