Dear all!

I have a problem: In baggage handling system, a voltage regulator 75kW (Sivolt - Siemens) drive 12 linear motors.
But now this product is phase out. Could I use a VFD to replace a Voltage regulator?
How to setting a VFD to change voltage but not change frequency (torque change)?

Please help me.
