Answer / gennadiy
Yes, the voltage in the simpliest V/f control is decreased proportionally with the speed decreasing. V~f in linear V/f control and V~f*f in parabolic V/f control (for pumps and fans).

Answer / h s sandhu
VFD means variable frequecy drive,If voltage is reduced then speed will reduce.
| Is This Answer Correct ? | 1 Yes | 0 No |
ifbthe motor is running in constant torque mode then decreasing the voltage will result in increase in frequency hence speed will increase in constant torque mode otherwise speed will decrease
