成形機
Document Type and Number:
Japanese Patent JP7467183
Kind Code:
B2
Abstract:
To provide a molding machine that regulates responsiveness of feedback control to an appropriate value.SOLUTION: A molding machine gives a target value to a servo amplifier in a molding operation to operate a serve motor (S31), and determines whether or not measured values detected by a sensor oscillate (S32). When it is determined that the measured values oscillate (S32: Yes), with a control parameter changed to a direction in which responsiveness to the target value decreases (S34), the molding operation is again performed (S35). When measured values oscillate in a first molding operation (S32: Yes), and measured values do not oscillate in the Nth (N is an integer of 2 or more) molding operation (S36: No), the servo motor is actually operated in order to mold a molding with a control parameter used in the Nth molding operation (S37).SELECTED DRAWING: Figure 5
