Digital Operator Functions

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% reference, and then continuously press the UP Key to incre-
ment the frequency reference by 0.01% only for the first 0.5 s, and then by 0.01% every 80 ms for 3 s thereaf-
ter. 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).
Prohibiting Writing Constants from the Digital Operator
If you set A1-01 to 0, you can refer to and set the A1 and A2 constant groups, and refer to drive mode, using
the Digital Operator.
If you set one of the constants H1-03 to H1-16 (multi-function contact input terminal S3 to S16 function selec-
tion) to 1B (write constants permitted), you can write constants from the digital operator when the terminal
that has been set is on. When the set terminal is off, writing constants other than the frequency reference is
prohibited. You can, however, reference constants.
