Machine automation drives from Omron
26 April 2010
The new MX2 inverter drives from Omron offer 200% starting torque, torque control in open loop, induction motor and permanent magnet motor control, one-parameter auto-tuning, drive sequence programming and in built position control functionality. They also incorporate safety functions, conforming with ISO 13849, and support Profibus, DeviceNet, EtherCAT or CompoNet. An intuitive flowchart programming tool allows the user to create programs with up to 1,000 lines of code and with 5 tasks running in parallel.
The MX2 can be configured to follow a master speed signal, with no additional hardware. In addition, the drives can be used for simple positioning tasks without the need for an external position controller. Up to eight positions plus home can be programmed by the user, and the drive can be switched between speed and position control as required.
To help address machine control safety requirements in line with ISO 13849-1 Cat 3, MX2 drives incorporate two safety inputs and an External Device Monitoring (EDM) output. This means that the requirement to use dual contactors on the drive output to perform safety functions is eliminated.
Modbus RS485 is built in, and option cards are planned for all key Fieldbus networks such as DeviceNet, Profibus and EtherCAT. A separate 24 VDC input is standard, and can be used to keep the drive operational in the event of a mains input failure.
Omron MX2 inverter drives for machine applications are available in 200V single-phase versions with ratings from 0.2 to 2.2kW, in 200V three-phase versions with ratings from 0.2 to 15kW and in 400V three-phase versions with ratings from 0.4 to 15kW.
