The Junma AC servo features a new plug-and-play design concept that requires no parameter settings or gain adjustments. The unit attains optimum servo performance without a time-consuming setup by accepting a pulse reference input from the host controller or PLC. After connection, users select the reference pulse switch setting on their amplifier to match the reference output on their controller. Connect the power and feedback cables and the motor is ready to run, providing high torque output at speeds up to 4,500 rpm. — Yaskawa America, Inc.
