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.
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.
Reference
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
- *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).
Linear Scale Resolution
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.
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.
Common Driver Sizes and Installation Methods
A mounting plate common to the CVD Series is used, and the same mounting hole pitch is used. Drivers with different connector orientations are available to match the installation method of your driver.
