„ 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 (shows the frequency reference)
• U1-02 (shows the output frequency)
• U1-05 (shows the motor speed)
• U1-20 (shows the output frequency after Soft Start)
• d1-01 to d1-17 (frequency reference parameters)
„ Switching between Monitors when the Power Supply is On
Using parameter o1-02, select the monitor item (U1-†† [status monitor]) to be displayed on the digital oper-
ator when the power supply is turned on. For information on monitors that may be displayed, refer to U1-††
in Chapter 5 Parameters and Settings.
Setting Precautions
If selecting monitor parameters other than U1-01 (shows the frequency reference), U1-02 (shows the output
frequency), and U1-03 (shows the output current), first select the monitor items to be displayed in o1-01, and
then set o1-02 to 4.

User Parameter
Default Value Allows storing of parameter settings as a User
Initialization Selection.
0: No Change
1: Set Defaults - Saves current parameter set-
tings as user initialization. A1-03 now
allows selecting <1110> for user initial-
ization and returns o2-03 to zero.
2: Clear All - Clears the currently saved user
initialization. A1-03 no longer allows
selecting <1110> and returns o2-03 to
zero.

Method Selection Determines if the DATA/ENTER key must be
used to input a frequency reference from the
digital operator.
0: Disabled. - DATA/ENTER key must be
pressed to enter a frequency reference.
1: Enabled. - DATA/ENTER key is not
required. The frequency reference is
adjusted by the up and down arrow keys
on the digital operator without having to
press the DATA/ENTER key.
