15.6.2 Speed Control Operation Combined with NC
This is the most popular operation using a main axis drive for a machine-tool. Sequence input signals such
as forward rotation and reverse rotation, and output signals such as zero speed and speed matching, are
connected to the I/O Module in the sequencer, and the speed references are connected to the axis control
module in the CPU. A basic connection example is shown in Fig. 15.30.
