RKII Series 5-Phase Stepper Motor Drivers (AC Input)

5-Phase Stepper Motor Drivers

RKII Series 5-Phase Stepper Motor Drivers

The RKII Series stepper motor driver is a high performance, energy saving stepper motor driver with a great low price. To achieve constant maximum torque output with low heat generation and save energy, the stepper motor and driver losses have been substantially reduced allowing to be operated for longer hours at high speed, which is not possible with conventional stepper motors and drivers. With simple wiring featuring screw-less connectors and side by side driver mounting, installation is easy and saves space.

  • High Efficiency, Low Vibration, Microstepping Driver
  • Stored Data (Network Compatible) Type or Pulse Input Type (use step angle switch to accept 1.8° pulse signals)
  • Built-in Protective Functions
  • Single-Phase 100-120 or Single-Phase 200-240 VAC

Pulse Input Type

High Efficiency

With conventional stepper motors in applications where heat generation had to be suppressed, the running current had to be reduced, which also reduces torque. With the RKII Series, thanks to its low heat generation and highly efficient motors, the motor torque can be used fully to maximize performance.

High Efficiency

Low Vibration, Microstepping Driver

Utilizing a full-time microstepping driver controlled by a digital system improves the vibration characteristics of the 0.72° stepper motor. Current control is also done by a high specification digital CPU. This model uses PWM control instead of PAM control resulting in a sinusoidal wave form in each phase, significantly reducing vibration.

Low Vibration


Space Saving Driver

The new RKII Series stepper motor driver was created by re-arranging the internal components and optimizing the usage of the space within the driver. The result, drivers can be installed side-by-side, reducing a significant amount of space.

Compact Driver

Protective Functions

Many types of protection functions are integrated into the driver. A blinking LED (blink count determines alarm type) indicates when an alarm is triggered.

Alarm Function

 

Easy Wiring

The new I/O connector does not require a screw and also eliminates the need for soldering or a special crimping tool. The motor connector can be connected easily by using a dedicated cable. This will reduce wiring time, maintenance and prevent mis-wiring.

Simple Wiring

Easy Connection


Electromagnetic Brake Control

The RKII (RKSD5) Drivers are cable of controlling the PKE5 (RKII Series 5 Phase Stepping Motors) build-in electromagnetic brakes (optional) on the back of the motor. This is an optional feature to be selected on the Pulse Input type drivers.

These brakes are non-excitation type electromagnetic brakes. When the power is accidentally cut off due to power outage or other unexpected event, the electromagnetic brake holds the load in position to prevent if from dropping or moving.


Stored Data (Network) Type Driver with Built-in Controller

Equipped with an Interface that Connects to Various Master Control Systems

FLEX

The RKII (RKSD5_D) Stored Data type driver offers industrial network communication under the FLEX concept, meaning the driver is equipped with an interface that connects to various industrial networks and master controllers featuring I/O; such as PLC, HMI or serial communication such as RS-485 / Modbus (RTU). FLEX is the generic name for products that are used for Factory Automation (FA) network control via I/O control, Modbus (RTU) control, or a network converter.

Network Connectivity

Three Connection Methods

  • I/O
  • Modbus (RTU) / RS-485
  • FA Network
FLEX connection options

I/O

The function of a built-in pulse generator lets you build an operation system by connecting directly to a PLC. Since no separate pulse generator is required, the drivers of this type saves space and simplifies systems.

I/O Communication

Modbus (RTU) / RS-485

Through RS-485 communication you can set operating data and parameters and input operation commands. A maximum of 31 drivers can be connected to one serial module. There is also a function for simultaneously starting multiple axes. The module supports the Modbus (RTU) protocol, which makes it easy to connect a PLC or similar device to the driver.

Mobus (RTU) / RS-485

FA Network

By using a Network Converter (sold separately), CC-Link, MECHATROLINK or EtherCAT communication is possible. Over these links, operating data and parameters can be set, and operation commands can be sent to the driver.

FA Network

Programming the Driver

The burden on the programmable PLC is reduced because the information necessary for motor operations is built into the driver. This simplifies the system configuration for multi-axis control. Set the data easily with control module (sold separately), data setting software or via RS-485 communication.

Programming the Driver

Group Sending Function

The group sending function simultaneously starts the multi-axes via Modbus (RTU) or FA network.

Send operation command to the main driver, other drivers in the same group will start operation simultaneously.

  • Modbus (RTU): Simultaneous start, change in distance, velocity and monitoring
  • FA Network: Simultaneous start only
