Set Values
• The following two methods are available to set the V/f pattern.
Select one of the 15 V/f patterns preset with the Inverter, in which case set n010 to 0, 1, 2,
3, 4, 5, 6, 7, 8, 9, A, b, C, d, or E.
Set n010 to F for an optional V/f pattern.
• The following are the V/f patterns preset with the Inverter.

Note
1. Set n010 so that the Inverter will produce high starting torque only in the following
cases.
The wiring distance between the Inverter and the motor is approximately 150 m or
more.
The motor requires high starting torque. The motor requires high starting torque if
the motor is connected a vertical-axis load.
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.
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 n011. 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.
