Features | Driver for 5-Phase Stepper Motor CVD Series Fully Closed-Loop Control Type

Fully Closed-Loop Control of Stepper Motors

At the start of positioning, open loop control is performed by taking advantage of the high response of the stepper motor, and position correction is performed using feedback from an external sensor once the position command is completed.

Fully Closed-Loop Control

High Precision Positioning

The difference in the feedback position relative to the command position is corrected by a fully closed-loop control that directly feeds back the position within the mechanism. It contributes to the design of equipment that requires submicron high-precision positioning.

Lost Motion*1 Measured Data

  • Open Loop Fully Closed-Loop
    0.51 μm 0.15 μm (target accuracy within ±0.2 μm)
  • Measurement Conditions

    • Feed screw lead 1 mm
    • Linear scale resolution 0.1 μm
    • In-Position Range: 1 cnt*2
    • Measured using laser measuring equipment
    • Lost Motion Measured Data
  • *1 This is the difference between the motor positioning in the CW and CCW directions relative to the target position and the stop position in the rotation direction.
  • *2 Position is corrected with a target error of 1 count of encoder pulses (-0.2~0.2 μm).

Stepper motor eliminates the need for gain adjustment and hunting

  • No Need for Gain Adjustment
    No need for gain adjustment to match the mechanism as is the case with servo motors. Since positioning operation does not always use encoder feedback, there is no need to adjust belt pulleys, cams, etc. to suit the mechanism and load.
  • Holding the Stop Position Without Hunting
    When positioning is completed, the motor stops by its own holding force without hunting. This is ideal for applications where vibration when stopping is a problem.
High Precision Positioning

Compatible with various external sensors to match the mechanism

Various types of sensors from various companies are supported, and feedback from the sensor type appropriate for the mechanism can be used.
