    摘要: This invention provides an acceleration control apparatus suitable for use as various kinds of feed control. A comparator circuit compares a command value supplied from an acceleration commanding unit and an actual value of acceleration detected by a signal generator connected to a motor to be controlled. A voltage command computing circuit provided at a rear stage of the comparator circuit effect predetermined processing of an acceleration deviation signal on the basis of the result of this comparison to output the resultant command voltage to a driving control circuit. This command voltage is output to the motor and thus acceleration of the motor is controlled.

    摘要: When a switching amplifier transitions into a power-off state, a switch is turned off and a power supply controller forcibly discharges a capacitor and forcibly reduces a reference potential with respect to a second power supply voltage. Since a logic power supply voltage reduces by the same amount as the reference potential, the logic power supply voltage from a viewpoint of the reference potential is fixed. A constant current circuit reduces a constant current according to the reduction in the reference potential with respect to the second power supply voltage, and reduces a first electric current and a second electric current. Before the logic power supply voltage from the viewpoint of the reference potential reduces, the first electric current and the second electric current are reduced, and an operation of a pulse generating unit can be ended in a normal state.

    摘要: When an output voltage from the amplifying circuit includes a positive DC voltage, an electric current continuously flows in a power source voltage, a load, and a reference voltage in this order. As a result, the reference voltage increases so as to be a first threshold voltage or more . The detecting section detects that the reference voltage is the first threshold voltage or more. When the output voltage from the amplifying circuit includes a negative DC voltage, an electric current continuously flows in the reference voltage, the load, a grounding potential in this order. As a result, the reference voltage reduces so as to be a second threshold voltage or less. The detecting section detects that the reference voltage is the second threshold voltage or less.

The amount of time from the start of the second period T2 until the voltage of the first integration circuit C1 reaches the reference voltage Vth is detected, and the amount of time from the start of the third period T3 until the voltage of the second integration circuit C2 reaches the reference voltage Vth is detected. The voltage of the first integration circuit C1 is kept at the reference voltage Vth from when the voltage of the first integration circuit C1 reaches the reference voltage Vth until the start of the third period T3, and the voltage of the second integration circuit C2 is kept at the reference voltage Vth from when the voltage of the second integration circuit C2 reaches the reference voltage Vth until the start of the fourth period T4. A pulse signal is generated, in which the pulse widths are equal to the amounts of time required for first and second integration circuits C1 and C2 to reach the reference voltage Vth.
