nInitializing Changed Parameter Values
You can save to the Inverter parameter set values that you have changed as parameter initial values. Change
the set values from the Inverter factory settings, and then set o2-03 to 1.
Set A1-03 (Initialize) to 1110 to initialize the Inverter parameters using the user-set initial values in memory.
To clear the user-set initial values in memory, set o2-03 to 2.
nSetting the Frequency Reference using the UP and DOWN Keys without Using the
Enter Key
Use this function when inputting frequency references from the Digital Operator. When o2-05 is set to 1, you
can increment and decrement the frequency reference using the UP and DOWN Keys without using the Enter
Key.
For example, enter the Run command using a 0 Hz reference, and then continuously press the UP Key to
increment the frequency reference by 0.01 Hz only for the first 0.5 s, and then by 0.01 Hz every 80 ms for 3 s
thereafter. Press and hold down the UP Key for 3 s minimum to reach the maximum output frequency 10 s
after that. The frequency reference that has been set will be stored in memory 5 s after the UP or DOWN Keys
are released.
nClearing Cumulative Operation Time
Set the cumulative operation time initial value in time units in parameter o2-07. Set o2-07 to 0 to clear U1-13
(Inverter Operating Time).
nClearing Inverter Cooling Fan Operation Time
Set the fan operation time initial value in time units in parameter o2-10. Set o2-10 to 0 to clear U1-40 (Cooling
Fan Operating Time).

Copying Parameters
The Digital Operator can perform the following three functions using the built-in EEPROM (non-volatile
memory).
•
Store Inverter parameter set values in the Digital Operator (READ)
Write parameter set values stored in the Digital Operator to the Inverter (COPY)
•
•
Compare parameter set values stored in the Digital Operator with Inverter parameters (VERIFY)
