Yaskawa America’s (www.yaskawa.com) Drives & Motion Division has launched the latest servo technology that offers a superior alternative to the usual stepper technology at similar price. The Junma AC Servo features a plug and play design that does not require gain adjustments or parameter settings.

Delivering optimum servo performance, Junma eliminates time consuming setup while accepting pulse reference input from the PLC or host controller. After connection, users can then choose the reference pulse switch settings on the amplifier that will match the controller’s reference output. Connecting the feedback and power cables enables the motor to run and deliver a maximum torque of 4,500 rpm.

With system parameters set on system power up, Junma’s machine load inertia is automatically calculated, while its tuning gains are dynamically adjusted, even during load changes, enabling the system to adjust to varying conditions.

Featuring advanced control functionality, Junma’s vibration suppression and adaptive tuning functions simplify the commissioning of the machine while maintaining optimum efficiency and high-precision positioning. Junma also features other functions such as homing to marker pulse, jogging, torque limiting and electronic gearing.

Customers can select from Junma’s four different servo motor and amplifier sets, which feature rated output ranging between 100W and 750W capable of both 200V and 100V input voltages. It also offers servo motor feedback with a 16-bit incremental encoder, offering resolution of 65,536 pulses per revolution.
