  Re: whether a separate starter is used for a motor while it is connected to a vvvf panel?
Answer
# 1
Seperate Starter is not required as the VVVF Panel will 
take care of starting the motor with its soft start feature.
ofcourse, in some applications, seperate starter is used to 
provide the bypass system.since in case of vvvf panel 
failure the motor can be operated through the starter.

# 2
In the V/F control technique the voltage to frequency ratio 
is maintained constant. Torque is maintained constant at 
rated frequencies and rated speeds .
