Emotron Vss Ac Drive User Manual

VSS series meets user’s needs and runs variety of applications like packaging, wood working, pumps, blowers, mixers and other machineries. It is ideal for machineries running on single phase supply, for better control and higher reliability. VSS drives are having host of features to meeting the demand for variety of applications. The sensorless vector control algorithm enables it to achieve speed control accuracy of upto 0.2% and starting torque of 180% at 0.25Hz. Rated as standard for heavy duty makes it ideal for demanding application needs. Features of VSS include programmable acceleration and deceleration curves, PID control, 16 programmable speeds, torque boost, DC brake, jog frequency, speed search, over excitation brake, torque control, separated V/f control and many more. This drive also brings with itself a host of readymade application macros which can simplify commissioning work and reduce the need for external controllers. In addition to logic functions like timers and comparators, VSS is having multi speed control, wobbulation control and length count functions.
