These parameters control the various functions, features, and display of the HOA keypad.
u o1: HOA Keypad Display Selection
These parameters determine the data display on the HOA keypad.
n o1-01: Drive Mode Unit Monitor Selection
The frequency reference display appears when the drive is powered up. Pressing the up arrow key will display the following
data: frequency reference → rotational direction → output frequency → output current → o1-01 selection.
Parameter o1-01 selects the content of the last monitor in this sequence.
No. Name Setting Range Default
o1-01 Drive Mode Unit Monitor Selection
104 to 699
U1-04 (Control Mode) to
U6-99 (Option Monitors 20)

<1> U2-oo and U3-oo parameters cannot be selected.
n o1-02: User Monitor Selection after Power Up
Selects which monitor parameter is displayed upon power up by entering the 1- oo part of U1-oo. Certain monitors are
not available in some control modes. Refer to U: Monitor Parameters on page 158 for a list of monitors.
No. Name Setting Range Default
o1-02 User Monitor Selection after Power Up 1 to 5 1
Setting 1: Frequency Reference (U1-01)
Setting 2: Motor Direction
Setting 3: Output Frequency (U1-02)
Setting 4: Output Current (U1-03)
Setting 5: User Monitor
The monitor value selected by o1-01 will be displayed.
n o1-03: HOA Keypad Display Selection
Sets the units used to display the frequency reference and output frequency. Set o1-03 to 3 for user-set units before setting
parameters o1-10 and o1-11.
No. Name Setting Range Default
o1-03 HOA Keypad Display Selection 0 to 3 0
Setting 0: 0.01 Hz Units
Setting 1: 0.01% Units (100% = Max Output Frequency)
Setting 2: r/min Units (Calculated by the Max Output Frequency and the Number of Motor Poles)
Setting 3: User-set Units (Use o1-10, o1-11)
Set the value used for the maximum frequency reference to o1-10. Set the placement of the decimal point in this number to
o1-11.
For example, to have the maximum output frequency displayed as “100.00”, set o1-10 = 1000 and o1-11 = 2 (i.e., 1000 with
2 decimal points).
Note: 1. Parameter o1-03 allows the programmer to change the units used in the following parameters and monitors:
U1-01: frequency reference
U1-02: output frequency
U1-16: output frequency after softstarter (accel/decel ramp generator)
d1-01 to d1-17: frequency references
2. Setting o1-03 to 2 requires entering the number of motor poles to E2-04 and E5-04.
