Note 1. Set n010 so that the Inverter will produce high starting torque only in the following cases.
S The wiring distance between the Inverter and the motor is approximately 150 m or more.
S The
motor requires high starting torque. The motor requires high starting torque if the motor
is connected a vertical-axis load.
S Power is input to or output from the Inverter through an AC or DC reactor.
Note 2. The set values of n012 to n018 will change automatically if any of the patterns listed in the
above table is selected.
Note 3. Refer to the following graphs for the characteristics of the V/f patterns.
The maximum voltage shown in each of the graphs is 200 V. The actual voltage, however,
corresponds to the set value of n011 (i.e., the rated input voltage of the motor). All voltage
values
will change in proportion to the set value of n01 1. For example, the default-set value of
n011 of the 400-V Inverter is 400 (V). Therefore, double all the voltage values when using the
400-V Inverter.
