The versatile RX inverter drive from OMRON
The RX is an advanced series of inverter drives for motors from 0.4 to 132kW. Omron understands that many sites contain variable speed drives from a number of suppliers so in designing the RX Series, in addition to performance, ease of use was prioritised to help reduce the number of overall steps required to get the motor running . It applies to cabling, setting parameters, commissioning, and on-site maintenance.
Its classification as a general purpose inverter is misleading: the RX offers a wide range of high performance features as standard, and can be further enhanced using option cards. For example, using the vector control and auto-tuning functions the RX Series can achieve high starting torque in excess of 200% at 0.3 Hz.
Other features and benefits include:
| FEATURE | BENEFIT |
| Sensorless vector control | Useful for up/down applications |
| Automatic energy-saving function | Automatically adjusts so that the Inverter output voltage during operation becomes minimum at a constant speed |
| Checks the direction and frequency of a naturally rotating load | Enables smooth restart of a free-running motor (e.g. fan motor) |
| Power-down braking | During a power failure RX Series can slow and stop the motor using the motor braking energy |
| ModBus-RTU communication | Inbuild basic networking |
| Inbuilt zero-phase reactor (radio noise filter) | Helps avoid EMC issues without additional filter |
