In the time chart, it takes time to start S renewal processing of CNC in .
A
At this time, both SWS1 and SWS2 signals are "0". Therefore, S command is not forwarded to any
spindle even when S renewal processing is completed.
It takes time to execute S renewal processing with selecting the objective spindle (SWS
X
=1) in "B" .
B
At this time, the 1st spindle (or the 2nd spindle) is selected, the renewal S command is forwarded to
the objective spindle after completing S renewal processing.
If "B" ends, please return all spindles to non-selected condition (SWS
X
=0).
B
Appendix 1
The part and the part are timer of ladder sequence.
A
B
As for X msec, please apply the value which suits the following condition.
In case of 1 path system : X msec > 64 msec •
•
•
•
In case of multi path system : X msec > 200 msec
Appendix 2
While machining by the constant surface control, the spindle must be always selected condition.
Please refer to "Relationship with other optional functions" described in multi spindle function on
"connection manual (function)".
