Lowest Vibration and Noise with Advanced Microstepping Control

The CVD driver offers superior low vibration and noise characteristics by using the new, fully digital full-time microstepping control circuit. The new Smooth Drive microstepping feature with higher current control reduces the basic step angle to a maximum resolution of 2048. As a result, significantly reduced step vibration in the low speed range is achieved. For the mid speed ranges, the vibration has been suppressed enabling a more stable torque characteristic.

Vibration Comparison

Significantly Improves Positional Accuracy When Microstepping

In general, stopping accuracy tends to be lower during microstep operation than with full step operation. The CVD significantly improves positional accuracy during microstepping compared to that of other similarly manufactures microstepping drivers or commonly used ICs.

Positioning Accuracy

Highest Torque with Bipolar Configuration (4 lead wire)

By utilizing the entire motor winding (Bipolar) higher start up and running torque can be achieved. For the optimal performance, consider a PKP Series Stepper motor or a CVK Series motor and driver package, for guaranteed results.

Small, Thin Microstepping Drive with Space Saving, High-Efficiency FETs

Improved, more efficient and smaller in design, allows for space saving by mounting the FETs on the bottom of the drive. The new FETs utilize less power than conventional FETs, producing less heat. For example, a 1.4A system now requires only 2.3W of power vs 7.3W. There is no requirement for a driver heat sink with the CVD Series drivers.

Selectable Step Angle and Run Current Control

The CVD driver has a step resolution switch to allow for matching the input pulse frequency of the controller. Simply use the step angle setting switch to set the input pulses desired. Output pulses are theoretical values as the Smooth Drive feature ensures maximum step performance operation of the stepper motor. The Smooth Drive microstepping control will still be utilized.

Smooth Drive is a function to achieve lower vibration and noise at low speed operation without changing the step angle setting. This function divides the step angle automatically in response to the pulse signals. There is no need to change the setting of the pulse signals (speed, number of pulses) on the controller side. Set the smooth drive function with the OFF/SD selection switch.

Driver Switches

Run Current

The motor current for when inputting pulses (operating current) can be changed with the RUN Current switch. If the load is small and there is an ample allowance for torque, motor temperature rise can be suppressed by setting a lower operating current. The operating current is a value in which the operating current rate is multiplied by the rated current (100%). Minimum current is 25% of rated and selectable in 5% increments.

The CVD Driver can also be used with lower amperage stepper motors. Use the Run Current Selection Switch to match the motor current ratings.

Standstill Current

When the motor stops, the current cutback function will be actuated to lower the motor current to the standstill current. The driver standstill current rate can be switched between 25% and 50% using the STOP switch. When setting the switch to the OFF side, the standstill current rate will be set to 25%. Then setting the switch to the ON side, the standstill current rate will be set to 50%.

2 Mounting Types and Connector Configurations

Bipolar Driver Types


Monitor the driver performance for early detection of any abnormalities. All CVD drivers have built in alarms to alert when there is a problem. The alarms are both a blinking LED and an Alarm signal to an upper controller. Alarms range from Overheat, Overvoltage, Overcurrent to EEPROM error and CPU error.

PKP Series 2-Phase Bipolar Stepper Motors

High-Torque 2-Phase bipolar stepper motors and Spur Gear (SH Type) stepper motors offer the optimum performance and value. In addition to offering high torque, the PKP series stepper motors offer more variety of electrical specifications, more frame sizes, encoder options and electromagnetic brake options for the right solution in stepper motors.

  • Offers 1.2 ~ 1.7 Time More Torque
  • 1.8° (200 pulse/rev) & 0.9° (400 pulse/rev)
  • SH Geared (Spur) Type for Inertia Matching & Higher Torque
  • Bipolar (4 lead wires)
  • Encoders - 200 or 400 Lines of Resolution
  • Electromagnetic Brake Type
