4.1 Description
The COSMOS 302X series inverters are designed for the simultaneous control of two three-phase asynchro-
nous motors; the electronic boards are housed inside a sturdy plastic case, and the dissipation of power is en-
sured by an aluminum heatsink. To ensure high reliability and quiet operation, they do not have a cooling fan
(“fanless”). All power connections are made via screw terminal blocks, while the connectors for the I/O, fieldbus
and encoder are detachable.
These devices implement a V / f scalar type control, with electronic protection on the output current delivered
and on the input power input:
The power section is made with the latest generation of intelligent IGBT modules, efficient and reliable. Various
diagnostic features are available to protect applications and the device itself.
The device is intended for integration into a control system equipped with a proprietary FLxIO fieldbus, which
allows a real-time control of the device with cycle times of 1 ms. The electrical connections are made using
standard Ethernet cables and connectors (cat.5e).
The inverter is also equipped with four 24V digital inputs for interfacing standard industrial sensors, and an in-
cremental encoder input for position / speed readings.
The COSMOS 302X series inverters have been designed for use in heavy industrial environments (“second
environment” as indicated in IEC 61800-3).
