„ Initializing Changed Parameter Values
You can save to the Drive parameter set values that you have changed as parameter initial values. Change the
set values from the Drive factory settings, and then set o2-03 to 1.
Set A1-03 (Initialize) to 1110 to initialize the Drive parameters using the user-set initial values in memory. To
clear the user-set initial values in memory, set o2-03 to 2.
„ Setting 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 0.01Hz only for the first 0.5 s, and then by 0.01Hz every 80ms 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.
„ Clearing 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
(drive Operating Time).
„ Clearing Drive 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).
