RX2-series Variable Frequency Drives Datasheet

Save energy and maximize performance with versatile inverter

This high performance inverter offers the same usability as the previous model and delivers improved usability: more efficient, easier, and faster.

High starting torque in open loop: 200% at 0.3 Hz, Full torque at 0 Hz in closed loop
Sensor-less and vector closed-loop control
Triple rating: VLD 110%/1min, LD 120%/1 min and ND 150%/1 min
Built-in EMC filter, logic programming and application functionality
Positioning functionality
Safe Torque Off (STO) according to EN ISO 13849-1:2008 (Safety Category 3/PLd) and IEC 60204-1 Stop Category 0
Communication options: Modbus, Modbus TCP
Regenerative solutions as option
CE, CULus, RoHS
Ratings: 200 V class three-phase 0.4 to 55 kW / 400 V three-phase 0.75 to 132 kW

Application customized

The RX2 Inverter can perform simple sequence control programmed for using support software CX-Drive. Crane control, tension control and other large-scale processes that require fast control speeds can be configured without a PLC, optimizing costs.

PM Motor Control

The RX2 Series can control permanent magnet motors (PM motors) as well as induction motors. Autotuning maximizes PM motor performance and helps saving energy.

Safety embedded

The RX2 Series features Safe Torque Off (STO) as a standard, to meet your machine safety needs.

Certified standards: IEC 61800-5-2:2016 STO SIL3 ISO 13849-1:2015 Cat.4 PLe

EtherCAT® - Coming soon

The EtherCAT option is available. Connect the RX2 inverters with the NX/NJ Machine Automation Controller to improve development and production productivity. Note: the EtherCAT unit will be coming soon.
