摘要： A control unit includes a position command generation unit generating a position command, a position control unit outputting a first speed command such that detected position tracks the position command, a pressure command generation unit generating a pressure command, a pressure control unit outputting a second speed command such that detected pressure or force tracks the pressure command, a speed command selection unit selecting creep speed, the first speed command, or the second speed command and outputs it as a speed command for the motor to operate; and a speed control unit outputting a current command for supplying current to the motor such that the motor speed tracks the speed command output by the speed command selection unit. After selecting the first speed command, the speed command selection unit selects the second speed command or the creep speed at timing when the first speed command falls below the creep speed.

摘要： A motor control device includes a power-consumption calculator that calculates a power loss L according to a motor current I or according to the motor current I and a motor velocity v, and calculates a motor output W from a product of the motor velocity v and a torque τ or thrust force, to determine whether a regenerative resistance is in an energized state. When the regenerative resistance is in an energized state, if a total value W+L of the power loss L and the motor output W is equal to or greater than 0 (W+L≧0), the power-consumption calculator calculates a power consumption P as W+L, and if a total value W+L of the power loss L and the motor output W is less than 0 (W+L

摘要： A motor control device. When the motor control device executes pressure control of which a minor loop is speed control or position control, the pressure control is executed in a manner that pressurization or depressurization is performed while a control parameter of the speed control is fixed; a control parameter of the pressure control is gradually increased; an oscillation amount is successively detected and stored. If the oscillation amount exceeds an acceptable value, on the basis of the control parameter of the pressure control and the oscillation amount stored during adjustment, the control parameter of the pressure control is adjusted such that the oscillation amount is equal to or less than the acceptable value.

摘要： A positioning control device according to an embodiment includes an amplifier that includes a converter that rectifies and outputs an AC power supply to bus-bars; a smoothing capacitor that smoothes an output of the converter and generates a bus voltage; a regenerative resistance and a regenerative transistor; an inverter that supplies a drive current; and a command generation unit that generates a position command value for positioning control of a mechanical load in accordance with a command pattern. The inverter is connected between the bus-bars and supplies the drive current. The command generation unit acquires a regenerative-power-amount estimated value and an energy value storable in the smoothing capacitor; and on the basis of a result of a comparison between these values, it decides whether to use the position command value on the basis of the command pattern.
