Yaskawa Releases Junma AC Servo

The Drives and Motion Division of Yaskawa America has introduced the Junma AC Servo, a device designed to make set-up a simple matter of connect and go.

The background:

The Junma AC Servo utilizes servo technology that provides a plug-and-play alternative to traditional stepper technology. It is designed to require no parameter settings or gain adjustments.

What: The goal of the plug-and-play concept is to attain optimum servo performance without time-consuming setup. According to Yaskawa, the Junma accepts a pulse reference input from the host controller or PLC (programmable logic controller). After connection, the user selects the reference pulse switch setting on the amplifier to match the reference output on the controllers. Connect the power and feedback cables, and the motor is ready to run, providing high torque output at speeds up to 4,500RPM.

Yaskawa says advanced control functionality is also available with Junma. Adaptive tuning and vibration suppression functions are designed to simplify machine commissioning while maintaining steady high-precision positioning and optimum efficiency. Other functions include jogging, homing to marker pulse, electronic gearing, and torque limiting.

Junma features four available servo motor and amplifier sets with rated outputs ranging from 100W to 750W capable of both 100V and 200V input voltages. Servo motor feedback is provided with a 16-bit incremental encoder, proving a resolution of 65,536 pulses per revolution. Additionally, Junma conforms to UL and DE industry standards and complies with the RoHS lead-free directive.

Price/availability: The Junma AC Servos are available on a quotation basis through Yaskawa dealers and distributors. Contact Yaskawa for more information.
