SJ300 Inverter

Free-setting V/f Pattern

The free-setting V/f inverter mode of operation uses voltage and frequency parameter pairs to define seven points on a V/f graph. This provides a way to define a multi-segment V/f curve that best suits your application.

The frequency settings do require that F1 ≤ F2 ≤ F3 ≤ F4 ≤ F5 ≤ F6 ≤ F7; their values must have this ascending order relationship. To satisfy this criterion during initial parameter editing, set F7 (B112) and work backwards when setting these values, since the defaults are all 0 Hz. However, the voltages V1 to V7 may either increase or decrease from one to the next. There- fore, you may set these parameters in any order.
