Frequency inverters of the ELVO
vert
SX series offer three different control methods:
V/f-characteristics for standard torque requirements and multi motor operation.
Sensorless Vector Control (SVC) for great torque especially at low frequencies (<5 Hz) and dynamic
compensation of slip with the usage of speed feedback. Using the operating data (output current, cos
ϕ
)
the frequency inverter for every load condition calculates the optimum output voltage or output frequency.
Vector Control (V2) with speed feedback using a pulse sensor or an incremental sensor for applications
which demand absolute accuracy of speed and angle (only with option board).
Remark:
Remark:
At the choice of 1, 2 or 3 the inverter automatically is switched to increased output power “P“.

For pos. 4 and 5 the correct adjustment of A1, A2 and A3 is essential !
The frequency inverter should be adapted optimally to the motor independent of the selected control method.
