Description

The HDT NTT240® series includes a complete range of digital single-axis servodrives for operation on 230VAC networks with current sizes up to 10A corresponding to nominal powers up to 3kW.
NTT240® allows the motor control of brushless, asynchronous servomotors, in direct current with permanent and linear magnets.
Piloting both from the analog reference and from the EtherCat, ProfiNet, CanOpen and Modbus protocols.
Feedback from incremental encoders, absolute and resolver encoders.
NTT240® integrates as standard the speed, torque, positioner, electric axis, electronic cam and pressure control.
An Ethernet port allows connection to the network and even the remote monitoring*. 
Easy to program, they connect via the USB port to the fast Caliper management software.
