AC servo drive NTT240

synchronousasynchronousbrushless

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. Control method Digital regulation, loop for torque, speed and position. - for AC brushless synchronous motor,rotary and linear: FOC control, SVM modulation, with feedback or sensorless. - for rotary asynchronous motor: V / Hz and FOC control, SVM modulation with feedback or sensorless. - for DC synchronous rotary brushless motor: trapezoidal modulation when using a feedback only from HALL sensors. - for permanent magnet continuos current motor (rotary) with encoder feedback Main reference Analog ± 10V differential speed and torque 16Bit Reference auxiliary Analog - ±10V differential speed, torque and position 12Bit Frequency reference Speed and position - Pulses and direction ( 2MHz ) - Incremental encoder A/B( 2MHz ) - CW/CCW ( 2MHz ) Optional fieldbuses - Modbus RTU - CanOpen Cia402> - EtherCat CoE ( DS402) - ProfiBus ProfiDrive DP v0
