Preset V/f Pattern

The following shows the preset V/f patterns. (The voltages are for 200V class. For 400V class, the value is twice that of
200V class.)

∗ 1 Consider the following items as the conditions for selecting a V/f pattern. They must be suitable for:
•
The voltage and frequency characteristics of motor.
•
The maximum rotation speed of motor.
∗ 2 Select high starting torque only in the following conditions. Normally, this selection is not required.
•
The wiring distance is long (150 meters (492 feet) and above).
•
Voltage drop at startup is large.
•
AC Reactor is inserted in the input or output of the Inverter.
•
A motor smaller than the nominal output of the Inverter is used.
∗ 3 Voltages when the models of 200V, 55kW or above, or 400V, 55kW or above are selected.
