Advocate transducer: Come from drawbench linear velocity (see on operation face plate) by AI2 serves as transducer advocate give, voltage of quantity of AO2 output imitate gives from machine use cascade to control a standard namely, come true advocate, from transducer speed synchronism, receive the stability that coil in order to maintain. From transducer (accept a plane) : The process open loop in complex process advocate give by advocate transducer is given, by AI1 input. P8.

00 measure feedback closed-loop control for imitate advocate give way, AI2 measures feedback closed-loop control for imitate advocate feedback gives way, both undertake PID adjustment. PID adjustment frequency and overlay of AI1 input frequency serve as together finally give from the frequency of machine. 4, note: After line has been received, observation lead plane is outputted (if not have, examination wiring is good) with whether to agree from machine input quantity.

The Kp of 03 correspondence, Ki, Kd is the compensatory parameter that adjusts to gain of PID closed circuit. General the action below the circumstance that this groups of parameter are coiling completely is the strongest, the action below the circumstance that the PID parameter of P8 group is coiling for nothing is the strongest, in both average is taken when coiling partly, notice two groups of parameter and the correspondence that receive a radius when parameter adjustment so, cooperate to use. Swing in what fork examines when starting extent, adjust P8 group and code of H form function, make fork moves optimal position, satisfy craft requirement of production. CNC Milling
