Reduction of total cost. PRICE & ENERGY SAVING Space Saving While achieving a significant improvement in motor performance, driver operations and functions, compared to conventional products, the RKⅡ Series has a new, low price. This new driver has been created by re-arranging the internal components, optimizing the usage of the size within the driver. In addition, drivers can be installed side by side, reducing a significant amount of space. ● When drivers are installed in contact with each other, the allowable ambient temperature range is 0 to 40°C High-efficiency with Low Price Slim &...

High Efficiency Lower Heat Generation Reduces power consumption by up to 47% Continuous Operation is Achieved By optimizing the motor material, 47% of the power consumption has been reduced. This results in the decrease of electricity and CO2 emission. In addition, with lower heat generated by the motor, there is a lesser requirement of fans or radiation plate. By utilizing high-efficient technology, continuous operation is achieved due to the reduction of motor heat. ● Power Consumption Comparison ● Motor Surface Temperature Operating Condition · Spin speed : 1000 r/min · Load torque: 0.47...

Built-In Controller Type compatible with FLEX. CONNECTION & NETWORK Example of connection and control with the Built-In Controller Type Using a Switch Box Operating data is set in the driver and the motor can be started or stopped simply by connecting a switch you have on hand. Control can be performed easily without using a PLC. Simple Control Using PLC (No positioning control module is required) When using PLC, you can built an operation system by connecting directly to an I/O Unit. A positioning unit is not necessary on the PLC side therefore space is saved and Stepper Motor Unit the...

FLEX is a generic name of the products which support Industrial Network control via I/O control, Modbus (RTU) control and network converter. Built-In Controller Type Modbus (RTU) control via PLC RS-485 communication can be used to set operating data, parameters and input operation commands. A maximum of 31 drivers can be connected to one serial unit. There is also a function for simultaneously starting multiple axes. The motor has a function that enables multiple shafts to be started simultaneously. The protocol supports Modbus (RTU), enabling connection with devices such as touch-screen...

| Performance and function to enhance High Accurate High Torque Shorten Positioning Positioning accuracy of the RKII Series is ±0.05° (± 3 arc min). When the RKII Series is used with a ball screw as shown in the below drawing, the stopping accuracy becomes ±1.4 pm. The accuracy of the normal ground ball screw is ±10 /vm, thus the accuracy is high enough for positioning operation. • Ball screw lead: 10 mm • Motor to be used: RKII series The RKII Series is compact and produc- es high torque. The torque of the 42 mm frame size model has increased 50%. This contributes to a reduction in...

Low Vibration Digital controlled 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. ● Current Waveform in Motor (theoretical figure) Step angle can be set easily For pulse input type, 32 step angles can be selected. To easily upgrade from a 1.8° stepper motor, use the step angle setting switch to...

® Standard Type with Encoder (Built-in controller type only) Encoder installed models make it possible to monitor the present position and detect • Positioning monitor This feature can be used to detect the position of the motor, for instance, compare the commanded position, to confirm normal using Z-phase signal Z-phase signal can be utilized to home return operation. Using Z-phase signal, the home return point will be detected with higher accuracy than single use of the home return sensor. The encoder will compare command position and encoder-count, if deviation exceeds set value a...
