Abstract:
1. A method for controlling an electric cylinder in a device, wherein the device comprises an electric cylinder that moves a rod, a load detector attached to the rod that detects the load for pressurizing applied to a material to be pressed, a servo motor that drives the electric cylinder, and a position detector attached to the servo motor that is electrically connected to a servo amplifier, wherein the servo amplifier is electrically connected to the servo motor and a servo controller and controls the drive of the servo motor, and wherein the servo controller is electrically connected to the load detector and the servo amplifier and outputs a position control command to the servo amplifier so as to control the position of the servo motor, the method comprising: a step S provides a command pulse signal for positioning from the servo controller to the servo amplifier based on the speed of the rod wherein the speed is input into the servo controller, a step S a step S a step S a step S a step S a step S
