D In operation mode, the frequency reference, output frequency, output current, and output voltage can
be monitored immediately if the factory settings are being used. One of these four values, the output
voltage, can be changed to a different value.
D When you want to monitor a value other than the output voltage, set that number in constant o1-01.
D Use the last two digits from the “U1 Monitor” list (U1-jj) to select a value. Refer to Table 4.3.

D Any one of the four values monitored at startup (frequency reference, output frequency, output current,
or the value set in constant o1-01) can be selected to appear when the power is turned ON.
D Change the setting of constant o1-02 to display an item other than the frequency reference at startup.

1 The frequency reference is displayed at start-up.
2 The output frequency is displayed at start-up.
3 The output current is displayed at start-up.
4 The value set in constant o1-01 is displayed at start-up.

5th digit = 3: .
The 1st to 4th digits of o1-03 determine the frequency setting
Ex 1:
To set the 100% speed to 200.0, set o1-03 to 12000.
200.0 will be displayed for 100%, 120 will be displayed for 60%.
Ex 2: To set the 100% speed to 65.00, set o1-03 to 26500.
65.00 will be displayed for 100%, 39.00 will be displayed for 60%.
Frequency Units of Constant Setting: o1-04
D This constant can be used to change the setting unit for V/f pattern constants to r/min.
