The spindle motor is closed by the KM3 main contact, and the main motor M1 is started according to SA5 selected steering.
When SB3 or SB4 is pressed, the KM3 coil is de-energized by the branch circuit, resulting in the KM3 main contact in the spindle rotation circuit.
Press the SB1 or SB2, through the 3,8,12, SB1 (or SB2), 13,14 branch, KM3 coil connected, and 16 area KM3 normally open auxiliary contact closed to form a self-locking.
The spindle motor M1 adopts the full-voltage starting mode. Before starting, the motor switch is selected by the combination switch SA5, the SQ71 in the control circuit is disconnected and the spindle motor is in normal working mode when the SQ72 is closed.
