PLC sample application (milling)
This sample application is applicable to machines with the following configurations:
● Three axes: axes X, Y and Z, with a hardware limit switch respectively in the positive and negative directions of each axis
● An analog spindle: SP (the fourth axis)
● PLC-controlled timely and quantitatively lubrication system
● PLC-controlled cooling system
