Editor's Notes
1 The Eco has been designed and is tailor-made by Siemens exclusively for HVAC applications. Family of Variable Speed Drives with common: software hardware layout user interface Fan & Pump Motors have variable torque-speed characteristics torque is proportional to the square of the speed, T=k x (rpm)2 this means a small low speed load torque and a large high speed load torque. load inertia (especially large fans) can be quite high so getting up to setpoint speed may take a few more seconds User Benefits of Variable Speed Drives overall energy and cost savings along with improved comfort levels through better regulation.
