Emerson Control Techniques SKB3400150 Commander SK 1.5 KW 3-phase 380–480 VAC Servo Drives

1.Overview of the Emerson Control Techniques SKB3400150

The Merserson Control Techniques SKB3400150 is a 1.5 kW, three-phase, 400 V-class servo drive. Measuring only 40 mm wide, it delivers 0-100% torque output in 0.1 seconds. Featuring built-in EtherCAT, Modbus-TCP, and CANopen multiprotocol buses, it automatically identifies motor parameters upon plugging in. Combined with a high-resolution 23-bit encoder interface, it achieves ±0.01 mm positioning accuracy and a 250 Hz speed loop response, reducing commissioning time by 50%.
