The CVD Series is a compact line of stepper motor drivers capable of handling a wide variety of applications. When used with the PKP Series Stepper Motors, the CVD Series offer the lowest vibration and noise with advanced microstepping control and the highest torque output.

The CVD Series drivers developed exclusively for the PKP Series stepper motors enables increased performance and functionality.

Industry's Top Compact, High Performance Driver

These compact and lightweight drivers contribute to saving space. The 2-phase and 5-phase drivers are identical in size, installation and I/O connectors. This allows for the selection and evaluation of 2-phase or 5-phase drivers based on the required specifications.

Select Drivers by Mounting Method

Drivers with different shapes and connector locations are available to match the mounting method.

High-Efficiency Design

The CVD Series provides increased torque by increasing the output current compared to conventional products. In order to allow the increase of output current, the design incorporates measures to reduce the amount of heat generated.

Low Vibration with Full-Time Microstepping

Low vibration and noise reduction have been achieved across all speed ranges by significantly improving the vibration level with the use of a fully digital-controlled full-time microstep driver. The CVD 5 phase driver and motor has further improved vibration characteristic.

There's a Wide Choice with 1.8° and 0.72°/0.36° Stepper Motors

The size, installation and I/O connectors for the CVD drivers and 1.8° or 0.72°/0.36° motors are the same. Because of this, it is easy to evaluate and select the proper package for the requirement.

Low Vibration Achieved by Full-Time Microstep Drive

The CVD Series is a fully digital control driver. Currents are controlled digitally and calculated by a high-performance CPU. The waveform of the current for each phase is changed from the conventional trapezoidal to sinusoidal, which allows for micro-step driving in all speed regions, and has reduced vibration even more.

 

This driver meets the needs for easy synchronized operation with pulse input type drivers.

I/O Signals

Different driver shapes and connection methods are available to meet a wide range of mounting locations.

Movement with Modbus (RTU) control? Simple data setting with touch screen? These drivers meet those needs.

Movement Examples

Simple Editing and Setting Operation Data and Parameters

Support Software MEXE02

Basic settings, such as operation data editing and parameter settings, can be easily made from a computer. Sequence control is also possible, making simple system confi guration possible without a host sequence.

Contributes to Visualization

Comes with a monitoring function that contributes to visualization.

Pulse Generator not Needed

The RS-485 communication type can set operation data in the driver, allowing for operation data to be selected and executed from a host. Operation data can also be linked.

Different driver shapes and connection methods are available to meet a wide range of mounting locations.

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 feedback position.

 

Enables High Precision Positioning

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 uses feedback from external sensors to correct the position.

 

Compatible with various encoders from a variety of manufacturers, allowing for feedback from the encoder best suited to the mechanism to be used.

• I/O signals are consolidated into a single EtherCAT communication cable. Wiring for communication, power supply, etc. for 4-axis are integrated into a single driver
• Reduces work hours for wiring and decreases problems from mis-wiring
• Integrated management of device information including motor information by using an EtherCAT master

• A single driver can control 2-phase/5-phase motors and actuators, which reduces parts inventory and management costs
• Synchronous control is possible while utilizing the different characteristics of 2-phase/5-phase motors via EtherCAT communication

Driver includes a function to acquire encoder information. Position deviation can be detected by the driver and outputs a signal without the need for a host controller. The actual position and speed of the motor can also be monitored on a computer screen by using the support software MEXE02.

• No high-speed counter needed, reducing host controller costs
• Outputs signal to the host controller using EtherCAT communication. Reduces program creation time.

• No electromagnetic brake control circuit is needed, which reduces program creation time
• Reduced wiring work time

Simple speed control with a stepper motor. Suppression of stop position variation in constant speed motors. These drivers meet those needs.

This product continues to rotate at the setting speed while forward (reverse) input is ON, but instantly tops when the input is OFF. Various operations can be achieved from the PLC depending on the length of time the forward (reverse) input is ON.

Using Stepper Motors

These motors are the answer to demands like keeping costs down with simple operations, and having a position holding function while stopped.

Using Constant Speed Motors and Inverters

Using a Stepper motor vs other motor types can improve stop position variation and sensor stopping accuracy.
