1. A controller for an injection molding machine, in which one driven member of the injection molding machine is driven by a plurality of axes, the controller comprising:
a physical quantity detection unit configured to detect one of physical quantities including an injection pressure, clamping force, moving platen position, and mold opening amount, which are controlled by the driven member; a speed command calculation unit configured to calculate a speed command value based on a deviation between the detected physical quantity and a command value; a synchronous error detection unit configured to detect a synchronous error between the axes; speed control units arranged in one-to-one correspondence with the axes; and a synchronous error correction unit configured to correct the speed command value based on the detected synchronous error for each of the axes, the speed control units being configured to calculate a torque command or a current command based on the corrected speed command value and a detected speed. |
