Changing Frequency Reference and Display Units
Set the Digital Operator frequency reference and display units using parameter o1-03. You can change the
units for the following parameters using o1-03.
•
U1-01 (Frequency Reference)
•
U1-02 (Output Frequency)
•
U1-05 (Motor Speed)
•
U1-20 (Output Frequency after Soft Start)
•
d1-01 to d1-04 and d1-17 (Frequency references)
Switching Monitors when the Power Supply Is ON
Using parameter o1-02 selects the monitor item (U1-
[status monitor]) that is to be displayed on the Digi-
tal Operator when the power supply is turned ON. For monitors that can be displayed, refer to U1-
in
Chapter 5 Parameters.
Setting Precautions
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 Digital
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. If the key is disabled, you cannot
use it to switch over the frequency reference source or the RUN-command source.
Initializing 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.
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 incre-
ment 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 there-
after. 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.
If selecting monitor parameters 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 (monitor selection) and then set
o1-02 to 4.
