Digital Operator Functions

Setting Precautions
If selecting monitor constants other than U1-01 (Frequency Reference), U1-02 (Output Frequency), and U1-
03 (Output Current), first select the monitor items to be displayed in o1-01, and then set o1-02 to 4.
Disabling the STOP Key
If b1-02 (Operation Method Selection) is set to 1, 2, or 3, the Stop Command from the STOP Key on the Dig-
ital Operator is an emergency Stop Command.
Set o2-02 to 0 to disable emergency Stop Commands from the STOP Key on the Digital Operator.
Disabling the LOCAL/REMOTE Key
Set o2-01 to 0 to disable the LOCAL/REMOTE Key on the Digital Operator. You cannot switch Inverter ref-
erence inputs set using reference inputs from the Digital Operator, b1-01 (Reference Selection), or b1-02
(Operation Method Selection).
Initializing Changed Constant Values
You can save to the Inverter constant set values that you have changed as constant 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 constants 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 0.01 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.
Clearing Cumulative Operation Time
Set the cumulative operation time initial value in time units in constant o2-07. Set o2-07 to 0 to clear U1-13
(Inverter Operating Time).
Clearing Inverter Cooling Fan Operation Time
Set the fan operation time initial value in time units in constant o2-10. Set o2-10 to 0 to clear U1-40 (Cooling
Fan Operating Time).
