* To switch to the 2nd control, allocate 08 (SET) to the multi-function input and then turn it on.
Control Method (V/f Characteristics)
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 regardless of the frequency.
Special Reduced Torque Characteristics (Special VP)
• Suitable for a fan or pump that requires torque in a low speed range. These have VC
characteristics only for low deceleration in reduced torque characteristics.
Period a: Provides constant torque characteristics (VC) within a range from 0 Hz to 10% of the base
frequency.
(Example) If the base frequency is 60 Hz, the Inverter provides constant torque
characteristics within a range from 0 to 6 Hz.
Period b: Provides reduced torque characteristics within a range from 10% to 100% of the base
frequency.
The Inverter outputs voltage based on a curve of the 1.7th power of the frequency.
Period c: Provides constant voltage within a range from the base frequency to the maximum
frequency.
