Control unit capable of smoothly carrying out a switching operation between position and pressure feedback control systems |
摘要 |
A control unit for an injection molding machine comprises a position feedback control system 41, a pressure feedback control system 42, and a velocity minor feedback control system 43 which is used in common to the position and the pressure feedback control systems 41 and 42. A minimum value selector 30-3 selects a smaller one of manipulated variables supplied from the position feedback control system 41 and the pressure feedback control system 42. During pressure control, a position pattern follower 30-4 controls the operation of a position pattern generator 24-2 so as to restart generation of a position pattern at any time.
