Can be used with 2-phase/5-phase stepper motors
EtherCAT communication enables synchronous operation
Automatically controls electromagnetic brakes using data acquired from integrated encoders, which can reduce host controller costs and program creation time
2 connector options (straight or right-angle) and 2 mounting options (with or without mounting plate)
Alarms
24 VDC Input / 0.3 ~ 2.8 A/Phase

EtherCAT Compatible/4-Axis Control Reduces Wiring and Saves Space

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

Daisy Chain Connection Reduces Wiring

Space-Saving Installation

The right-angle connector direction type allows for more space-saving installation without the interference of wires, even when multiple units are placed side by side.

Simple Wiring

Connector positions are concentrated on 2 sides. Wiring can be simplified and organized.

Driver Cover (Sold separately)

Compatible Driver: With mounting plate

Cover to prevent foreign objects from falling onto the driver
Complies with degree of protection IP20

PADC-CVD4ARED

Combined Use of 2-Phase/5-Phase Motors and Synchronous Control is Possible Using EtherCAT Communication

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

Product Lineup and Application Example

The lineup of 2-axis driver now allows layouts to be fit the equipment space.

4-Axis Driver

NEW 2-Axis Driver

Example Applications for 2-Axis Driver

XY Stage

Loader/Unloader

Conveyor

Acquire Encoder Information and Position Deviation Detection

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.

Acquire Encoder Information and Position Deviation Detection

The Encoder Detection Information can be Monitored Using the Support Software MEXE02 (Free)

Acquire Encoder Information and Position Deviation Detection

Automatic Control of Electromagnetic Brake and Power Supply

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

Automatic Control of Electromagnetic Brake and Power Supply

Can Provide Power to Sensors

Other Functions

Alarm Output

Output of an excessive position deviation alarm allows for detection of motor misstep/stepout (Main circuit overheat alarm, etc. can also be output)

Information

Output of an excessive position deviation alarm allows for detection of motor misstep/stepout (Main circuit overheat alarm, etc. can also be output)
Can be monitored using EtherCAT communication

Separation of Main Power and Control Power

Other Functions

Supports addition of a separate external safety relay to shut off the main power supply
Monitoring, etc. via EtherCAT communication is possible even when the main power supply is shut off

Main Power Supply Inrush Current Suppression Function

This function protects the circuits in the main power supply unit from inrush currents that occur when the main power supply is turned on.
