User-friendly variable speed drive

Supplier News

EUROTHERM's new 650 series of ac variable speed drives has been specifically designed to provide simple, no-fuss speed control of standard three phase ac induction motors from 0.2 to 90kW.

New technology components have allowed an over all space reduction of up to 40 per cent over current similarly sized drives. No side ventilation also allows for reduced cabinet size as the DIN rail mounting 650 requires zero clearance between drives.

User-selectable pre-programmed applications allow the 650 to be working in minutes. Simply select the relevant application from the menu list and the drive's inputs/outputs parameter list is automatically configured.

The operator can select from five standard preset applications: basic speed control, auto/manual control, preset speeds, raise/lower control or PID control. Once selected the 650 automatically configures the input and output parameter list.

The 650 series is provided with a fully featured operator/programming control display. This display features a large backlit four digit LCD display, with motor direction and rotation display, parameter units, diagnostic indicator and six simple control buttons for local start/stop, raise/lower and program menu. The op station can also be locally or remote mounted.

Provided with inbuilt RFI filters as standard up to 7.5kW, further reduces cost and space. For field flexibility the 650 is provided with eight preset speeds, a voltage free contact output and two programmable logic I/O.

The 650 can accept two analog inputs and for load or speed control an analog output is also available. A motor thermistor input is also provided. Eurotherm Australia 02 9634 8444.
