5.10 o: Operator Related Settings
5.10 o: Operator Related Settings
These parameters are for controlling the various functions, features, and display of the digital operator.
◆ o1: Digital Operator Display Selection
These parameters determine how data appears on the operator display.
■
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 lets the user select the content of the last monitor in this sequence.
■
o1-02: User Monitor Selection after Power Up
Selects which monitor parameter is displayed upon power up. This is done by entering the 1 part of U1-. Certain
monitors are not available in some control modes. Refer to U: Monitor Parameters on page 291 for a list of monitors.
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-selected monitor (set by o1-01)
■ o1-03: Digital Operator Display Selection
Sets the units used to display the frequency reference and output frequency. Set o1-03 to 3 for user-set units, then set
parameters o1-10 and o1-11.
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 no. of motor poles)
Setting 3: User-set units (use o1-10, o1-11)
Set the value use for the maximum frequency reference to o1-10. The placement of the decimal point in this number
should be set to o1-11.
For example, to have the maximum output frequency displayed as “100.00”, set the 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:
x U1-01: frequency reference
x U1-02: output frequency
x U1-05: motor speed
x U1-16: output frequency after softstarter (accel/decel ramp generator)
x d1-01 to d1-17: frequency references
2. Setting o1-03 to 2 requires that the number of motor poles be entered to E2-04, E4-04, and E5-04.
