Functions
Control Method (V/f Characteristics)
You can set V/f characteristics (output voltage/output frequency).
* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it
on.
*1. Refer to "Sensorless Vector Control" (page 4-116).
*2. Refer to "0-Hz Sensorless Vector Control" (page 4-117).
Constant Torque Characteristics (VC)
Output voltage is proportional to output frequency.
While proportional from 0 Hz to base frequency, the output voltage is constant from base to
maximum frequencies.
