Units of UF-I30 series
Are intended for additional installation into machines and equipment, where it is desirable to continuously or stepwise control the speed of the asynchronous engine or engines.
The UF-I30 unit gives us the opportunity to get a lot of benefits when rebuilding the system with direct drive motors. The basic advantage is a continuous speed control by a remote control directly from the control panel. The operator controls the engine speed continuously within a set range, which can reach up to 10-200% of rated speed.
When connecting the UF-I30 unit to the hierarchy of the entire control system, it is possible to control the engine speed automatically using a higher level of the control system.
Other advantages of this solution are also motor start, built-in protection features and reducing mechanical wear of the consequential equipment. In addition to potential energy savings (by the application up to 70%), there are also cost savings. Therefore, using the frequency converters even in new areas is extremely attractive and often necessary. As examples, can serve installations replacing throttle valves at pump devices or replacement of mechanically adjustable gears in traffic engineering. Similarly it is with machinery such as saws and drills, where a complex gear setup such as cascade pulley or variator are successfully replaced.
Nowadays, the frequency converter often replaces the still often used method of acceleration of asynchronous motors by switching star / delta.
A single UF-I30 unit can control multiple separate motors, it is only necessary to properly dimension the performance of the unit according to the number of individual motors and their nominal currents.
