3G3RX customisable frequency inverter drives from Omron UK
The RX Series of general purpose drives from Omron UK are available with ratings up to 132 kW and feature an extensive range of built-in and customisable application functions, such as brake control, bypass motor control, orientation stop and automatic energy saving optimisation for fan and pump applications.
The RX can handle simple positioning tasks without the need for an external motion controller; among the facilities offered for positioning applications are homing and position teaching. The drives can be switched instantly between speed and position control, as required.
Position commands, speed commands and acceleration/deceleration times are set in parameters up to 8-strp positioning. The teaching function can also be used to store positioning points in memory by actually moving the machines. There are two types of positioning commands with absolute values and interrupt feeding
Built-in advanced functionality
The 3G3RX has built-in application functionality and configurable user programming. For example, simple positioning is handled by the inverter without the need for an external controller. Functions include pulse train position control mode, homing and position teaching.
With Electronic Line Shaft synchronisation it is possible to achieve master and slave position locking, again without the need for an external controller or special firmware. The Electronic Line Shaft Application Software is for position and speed follower applications, allowing a slave drive to precisely follow a master encoder. It is the ideal solution for dual-motor synchronised applications.
Additionally, a simple to read and set 5 line LCD text operator is standard. Ten languages are supported, and a real time clock and calendar. Other key features include:
– Up to 132 kW (200 HP)
– Built-in EMC filter
– Sensor-less and vector closed-loop control
– High starting torque in open loop (200% at 0.3 Hz)
-Full torque at 0 Hz in closed loop
– Built-in logic programmability
– Built-in application functionality
– Automatic energy saving
– Built-in Modbus RS485 (options for other networks incl. DeviceNet, PROFIBUS, MECHATROLINK-II, EtherCAT, CC-Link and CompoNet)
