Driver for 5-Phase Stepper Motors Fully Closed-Loop Control Type A fully closed-loop control type product line has been added to the CVD Series. It retains the ease of use of a stepper motor and enables high positioning accuracy operation when combined with external sensors. With Installation Plate: CVD5B-KF Right Angle with Installation Plate: CVD5BR-KF These are useful in facilities and equipment that require highly accurate control. Enables High Positioning Accuracy The use of fully closed-loop control, which provides direct feedback for the mechanism position, allows for the correction of any deviations between the command position and the detected position. Target Position Position Correction To Accurate Positioning within Submicron* A-Phase B-Phase Position Feedback (Encoder Pulse) *Oriental Motor reference: Under actual measurement data conditions Reference: Actual Measurement Data Actual measurement data for lost motion (positioning of the motor in the CW and CCW directions compared to the target position, and the difference from the target position at that time). Open Loop Control Fully Closed-Loop Control Feed screw lead 1 mm Linear scale resolution 0.1 μm Measurement using laser Measurement error of ±0.2 ppm for traveling amount Fully Closed-Loop Stepper Motor Control The CVD Series fully closed-loop control type uses open loop control at the start of positioning to take advantage of the high response of the stepper motor. After the positioning command has been completed, it transitions to fully closed-loop control using feedback from external sensors to correct the position.

Retains the Advantages of Stepper Motors Holding the Stop Position without Hunting When positioning is completed, the motor stops with its own holding force without hunting. This is ideal for applications where absence of vibration upon stopping is required. No Gain Adjustment Required Unlike servo motors, gain adjustment to match the mechanism is not necessary. Because the positioning operation does not use the usual feedback from an encoder, there’s no need for the adjustment of mechanisms, such as belt pulleys or cams, or for load adjustments. High-precision positioning without gain...
