6. Applications This chapter contains tables giving an overview of many different applications/duties in which it is suitable to use variable speed drives from OMRON. Further on you will find application examples of the most common applications and solutions. s 6.1 Application overview 6.1.1 Pumps Challenge OMRON SX-V solution Menu High start currents require larger fuses and cables. Cause stress on equipment and higher energy cost. Dry-running, cavitation and overheating damage the pump and cause downtime. Sludge sticks to impeller when pump has been running at low speed or been stationary for a while. Reduces the pump’s efficiency. Motor runs at same speed despite varying demands in pressure/flow. Energy is lost and equipment stressed. Process inefficiency due to e.g. a blocked pipe, a valve not fully opened or a worn impeller. Water hammer damages the pump when stopped. Mechanical stress on pipes, valves, gaskets, seals. Torque control reduces start current. Same fuses can be used as those required for the motor. Pump Curve Protection detects deviation. Sends warning or activates safety stop. Automatic pump rinsing function: pump is set to run at full speed at certain intervals, then return to normal speed. PID continuously adapts pressure/flow to the level required. Sleep function activated when none is needed. Pump Curve Protection detects deviation. Warning is sent or safety stop activated. Smooth linear stops protect the equipment. Eliminates need for costly motorized valves. 331–336, 351 411–419, 41C1– 41C9 362–368, 560, 640 320, 380, 342, 354 411–419, 41C1–41C9 331–336 6.1.2 Fans Challenge OMRON SX-V solution Menu High start currents require larger fuses and cables. Cause stress on equipment and higher energy cost. Starting a fan rotating in the wrong direction can be critical, e.g. a tunnel fan in event of a fire. Draft causes turned off fan to rotate the wrong way. Starting causes high current peaks and mechanical stress. Regulating pressure/flow with dampers causes high energy consumption and equipment wear. Motor runs at same speed despite varying demands in pressure/flow. Energy is lost and equipment stressed. Process inefficiency due to e.g. a blocked filter, a damper not fully opened or a worn belt. Torque control reduces start current. Same fuses can be used as those required for the motor. Fan is started at low speed to ensure correct direction and proper function. Motor is gradually slowed to complete stop before starting. Avoids blown fuses and breakdown. Automatic regulation of pressure/flow with motor speed gives more exact control. PID continuously adapts to the level required. Sleep function is activated when none is needed. Load Curve Protection detects deviation. Warning is sent or safety stop activated. 331–336, 351 219, 341 219, 33A, 335 321, 354 320, 380, 342, 354 411–419, 41C1–41C9 Omron SX inverter manual Applications 33
6.1.3 Compressors Challenge OMRON SX-V solution Menu High start currents require larger fuses and cables. Cause stress on equipment and higher energy cost. Compressor is damaged when cooling media enters the compressor screw. Pressure is higher than needed, causing leaks, stress on the equipment and excessive air use. Motor runs at same speed when no air is compressed. Energy is lost and equipment stressed. Process inefficiency and energy wasted due to e.g. the compressor idling. Torque control reduces start current. Same fuses can be used as those required for the motor. Overload situation is quickly detected and safety stop can be activated to avoid breakdown. Load Curve Protection function detects deviation. Warning is sent or safety stop activated. PID continuously adapts to the level required. Sleep function activated when none is needed. Load Curve Protection quickly detects deviation. Warning is sent or safety stop activated. 331– 336, 351 411–41A 411–419, 41C1–41C9 320, 380, 342, 354 411–419, 41C1–41C9 6.1.4 Blowers Challenge OMRON SX-V solution Menu High start currents require larger fuses and cables. Cause stress on equipment and higher energy cost. Difficult to compensate for pressure fluctuations. Wasted energy and risk of production stop. Motor runs at same speed despite varying demands. Energy is lost and equipment stressed. Process inefficiency due to e.g. a broken damper, a valve not fully opened or a worn belt. Torque control reduces start current. Same fuses can be used as those required for the motor. PID function continuously adapts pressure to the level required. PID continuously adapts air flow to level required. Sleep function activated when none is needed. Load Curve Protection quickly detects deviation. Warning is sent or safety stop activated. 331–336, 351 320, 380 320, 380, 342, 354 411–419, 41C1–41C9 34 Applications Omron SX inverter manual
