(1) Constant torque characteristic (VC)
Output voltage outputs proportionally to the output frequency.
Output voltage outputs proportionally from 0 to the base frequency, but the output voltage from the base
frequency to the maximum frequency is constant regardless of frequency.
(2) Reduced torque characteristic (VP1.7 power)
This characteristic can be used when a large starting torque isn’t required.
At low speeds, it can cause improvement of efficiency, low noise and low vibration because of lowering
the
output voltage. V/f characteristic is as follows.
