    摘要: A command value generating circuit determines an acceleration profile indicating changes in acceleration of a mechanical load over time. The acceleration profile is determined such that the mechanical load is accelerated from a stop at a first position to a peak velocity, and is decelerated from the peak velocity to stop at a second position, and that the absolute value of an acceleration during accelerating and decelerating the mechanical load is equal to or less than an upper limit acceleration, and that the acceleration is maintained at the upper limit acceleration for a period of time from starting to accelerate the mechanical load, and then, gradually decreased from the upper limit acceleration. The command value generating circuit determines a velocity profile indicating changes in the velocity of the mechanical load over time, according to the acceleration profile, and generates a position command value, according to the velocity profile.

    摘要: A motor control device main unit includes a pressure command signal generation module, a pressure control module, a speed control module, and a current control module. The pressure command signal generation module of the motor control device main unit generates a pressure command value so that a derivative of the pressure command value is equal to or less than a product of an elastic constant of the pressurized target and a maximum motor speed. The pressure control module carries out pressure control calculation to calculate a motor speed command value based on a deviation between the pressure command value and an actual pressure value, and generates a motor speed command signal, which is a signal of the motor speed command value.

    摘要: The present disclosure relates to a chemically treated zinc-based plated steel sheet that is superior in weather resistance, water resistance, blackening resistance and film adhesion. A chemical conversion film having a thickness 0.5-10 μm is formed by coating and drying a chemical treatment solution on a surface of an aluminum-containing zinc-based alloy plated steel sheet. The chemical treatment solution contains a fluororesin containing 0.05-5% by weight of a hydrophilic functional group selected from the group consisting of a carboxyl group and a sulfonic acid group and 7-20% by weight of a fluorine atom, the fluororesin in which a number-average molecular weight is 1,000-2,000,000, and an oxoate, a fluoride, a hydroxide, an organic salt, a carbonate or a peroxygenated salt of a group 4A metal.
