This motion control card can be controlled four axles simultaneously, and each axle has A phase, B phase and the Z phase input signal of three pairs of difference, and EA and EB signal are used for carrying out position calculation, and EZ signal is as initial point index signal.Each axle has an origin switch signal, inputs to search the initial point of this axle by mechanical origin signal, can pass through software set origin switch pattern.Each axle has two position limit signal EL+ (forward is spacing) and EL-(oppositely spacing), can pass through software set limit switch pattern.When concrete enforcement, the pulse signal of the encoder for servo motor feedback of C axle and Z axis all accesses motion control card.Because every axle motion initially has individual start bit, therefore need to use initial point signal, software is determined start bit by search initial point signal.C axle is direction of rotation, does not need positive and negative spacingly, only adopts an initial point signal.Z axis, except initial point signal, also accesses positive and negative two position limit signals, two spacing shielding.General digital input/output port also can be used to connect some switching signals.
For single shaft motion, divide according to move distance: this motion control card has fixed length operational mode and continuous operation mode; Divide according to movement velocity: this motion control card has trapezoidal speed operational mode and S curve motion pattern.S curve motion pattern is used for allowing an axle with S curve speed operation specific pulse number, and vibration when S curve motion pattern can effectively be eliminated and improve acceleration and deceleration, makes motion very level and smooth.Have more advantage in trapezoidal speed operational mode as above-mentioned said S curve motion pattern, the control system in the present embodiment all adopts S curve motion pattern.Before scanning starts, in order to measure the straight length that is scanned part 5, need to be scanned part 5 and turn over certain angle, at this moment adopt fixed length operational mode; In scanning process, Z axis and C axle are carried out simultaneously but independently motion, and are continuous motions, ensure the speed motion in certain proportion of these two axles simultaneously, be scanned the 3-D scanning of part 5 data, thereby obtain being scanned part 5 three-dimensional data files thereby realize.
Because this control system is higher to requirement of real-time, motion control card transmitted, to motor driver, requires motor to send out immediately pulse, must not postpone, and acts without fail.Therefore this control system adopts servo electrical machinery system.Because it is high that servomotor has control precision, stronger overload capacity, the series of advantages such as speed responsive performance is good, and runnability is reliable.When concrete enforcement, select Panasonic full digital AC servo driver MSDA0231A1A, the servomotor of configuration is MSM022A1.The rated output power of driver institute translator is 1.5kw, and rotary encoder is incremental 2500P/r, and input power is 3 phase 220V, and normal speed is 2000r/m.
