5. An apparatus for controlling motor, comprising:
-
a serial data communication portion;
a reception-processing portion for receiving information which is addressed to its own address and supplied from a host device via said serial data communication portion;
an A/D converting portion for converting voltage corresponding to a present position of an object to be controlled supplied from a position detecting portion into present position data having n-bit;
an electric motor type actuator; and
an actuator driving controlling portion for driving said electric motor type actuator based on a deviation between data on a target value having n-bit included in the received information and said present position data having the n-bit such that the position of said object to be controlled becomes a position of said target value, wherein said actuator driving controlling portion is provided with means for controlling deceleration which, when the deviation between said target value data having the n-bit and said present position data having the n-bit becomes less than a previously set judgment value of starting of deceleration control, drives said electric motor type actuator by PWM control with a duty ratio previously set corresponding to said deviation, and rotates and drives the electric motor type actuator in an ON-duty period within a PWM cycle, and applies a regeneration brake to said electric motor type actuator in an OFF-duty period within the PWM cycle. - View Dependent Claims (6, 7, 8, 9, 10)
