Description

The HDT NTT460® series includes a complete range of digital single-axis servodrives for operation on 400VAC networks with current sizes up to 200A corresponding to nominal powers up to 130kW. NTT460® allows the motor control of brushless servomotors, asynchronous, DC MP and also linear motors. Piloting both from the analog reference and from the EtherCat, ProfiNet, CanOpen and Modbus protocol. Feedback from incremental encoders, absolute and resolver encoders. NTT460® integrates as standard the speed control, torque, the positioner, the electric axis, the electronic cam and the pressure control. An Ethernet port allows connection to the corporate network and even remote monitoring. Easy to program, they connect via the USB port to the fast Caliper management software
