10.6.1 Multiple Spindle Control II
Function and purpose
Multiple spindle control II is a function that designates which spindle to select with the signals from
PLC. The command is issued to the spindle with one S command.
Detailed description
(1) Spindle command selection, spindle selection
The S command to the spindle is output as the rotation speed command to the selected spindle
when the spindle selection signal (SWS) from the PLC turns ON. The selected spindle rotates
at the output rotation speed. The spindle whose selection is canceled when the spindle
selection signal (SWS) turns OFF maintains the speed at which it was rotating at before being
canceled. This allows each axis to be simultaneously rotated at differing rotation speeds. The
spindle command selection signal is used to determine which part system each spindle
receives the S command from.
