VLB30220A480 - Lovato - Variable speed drive

<h3>Variable speed drive for motor control</h3><p>This variable speed drive controls a motor by adjusting speed according to the machine command instead of using fixed-speed switching. It is used in automation panels for pumps, fans, conveyors and industrial machines where motor speed, process response and energy use must be managed from the control system.</p><h4>Speed regulation and drive integration</h4><p>motor power 22 kW; supply and motor voltage data 400-480 VAC 50/60 Hz, 400 V. The drive must be selected according to motor power, supply network and the voltage level required by the application. The integrated EMC filter category, when specified, helps define the installation context and the expected wiring practice. Power units are integrated with the logic or control section required by the drive architecture.</p><h4>Commissioning and maintenance</h4><p>During commissioning, keep motor data, supply data, control terminals, communication modules and any braking or line components aligned with the electrical diagram. Parameter access through keypad, PC link or communication option should be documented with the machine sequence. This makes later service clearer and avoids confusing power wiring with signal wiring.</p><p>For replacement, compare power rating, supply type, EMC filter indication and communication or keypad options before disconnecting the installed drive. A clear record of parameter access and motor feeder assignment helps restore operation without changing the intended control logic.</p><p>For service work, record the motor data set, speed reference input, start and stop command path and any fieldbus option. This keeps parameter recovery clear after replacement and separates drive settings from the external machine logic.</p> <h3>Variable speed drive for motor control</h3><p>This variable speed drive controls a motor by adjusting speed according to the machine command instead of using fixed-speed switching.
