The setting of rated values for carrier frequencies [bb101]/[bb201] are internally limited in accordance with the description. Also, it is recommended to set values equivalent to or above (maximum output frequency for driving ×10) Hz for the setting of carrier frequencies [bb101]/[bb201]. Also, in the case of induction motor (IM) control, for items other than those subject to V/f control, it is recommended to set carrier frequency at 2 kHz or more. In the case of synchronous motor (SM)/permanent magnet motor (PMM) control, it is recommended to set carrier frequency at 8 kHz or more.

Features

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®

The EtherCAT option is available. Connect the RX2 Inverters with the NX/NJ Machine Automation Controller to improve development and production productivity. Both configurations are possible, Standard and Ring topology.
