* These values are for the 220V class; double the values for 440V class inverters.
† Consider the following items as the conditions for selecting a V/f pattern.
They must be suitable for
(1) The voltage and frequency characteristic of motor.
(2) The maximum speed of motor.
‡ Select high starting torque only in the following conditions. Normally, the
selection if not required.
(1) The power cable length is long [492ft (150m) and above].
(2) Voltage drop at startup is large.
(3) AC reactor is inserted at the input side or output side of the inverter.
(4) A motor with capacity smaller than the maximum applicable inverter capacity
is used.
