Technical Data


The TMC460Evo® series by HDT includes a complete range of digital servo drives in single-axis execution for operation on 400VAC networks with current sizes up to 3A corresponding to nominal powers up to 2W.
TMC460Evo® allows the motor control of brushless, asynchronous, DC PM and linear servomotors.Piloting both from analog reference and from EtherCat, ProfiNet, CanOpen and Modbus protocol.
Feedback from incremental encoders, SSI absolute encoder and resolver.
TMC460Evo® integrates speed, torque, positioner, electric axis, electronic cam and pressure control as standard.
An Ethernet port allows connection to the corporate network and also remote monitoring.
Easy to program, they connect via the USB port to the fast Caliper management software..
