CONTROL SYSTEM SUITABLE FOR GLASSWARE FORMING MACHINE
摘要
A control system for a member driven by the pneumatic piston and cylinder (15) under the control of a solenoid driven proportional pneumatic valve (16) which receives valve command signals from a servo control card (32) which includes a microprocessor and a memory, the card repetitively calculating acceleration-limited values for the command signals on the basis of an algorithm and a motion profile stored in the memory, the values used in computing the algorithm being derived from transducers (25, 26, 27) which sense the pressures of opposite sides of the piston and the position of the driven member.
