13 Spindle Control

13.9 Multiple-Spindle Control II

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.

 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.
