Frequency Display Unit Selection

Sets the display units for the frequency reference and output frequency.

Determined by A1-02

(0 - 3)
Note:

  • Select the setting unit of these parameters:

    • d1-01 to d1-17 [Reference 1 to 17]

    • U1-01 [Frequency Reference]

    • U1-02 [Output Frequency]

    • U1-05 [Motor Speed]

    • U1-16 [SFS Output Frequency]

    • U4-14 [PeakHold Output Freq]

  • For monitor 2, the setting value is always 0 [Hz Unit].

0
0.01 Hz
 
1
0.01% (100% = E1-04)

The maximum output frequency is 100%.

2
min-1 (r/min) units

The drive uses the maximum output frequency and number of motor poles to calculate this value automatically.

Note:

When you set o1-03 = 2 [min-1 (r/min) units], make sure that you set the number of motor poles in these parameters:

  • E2-04 [Motor Pole Count]

  • E4-04 [Motor 2 Motor Poles]

  • E5-04 [PM Motor Pole Count]

  • E9-08 [Number of Poles]

3
User Units (o1-10 & o1-11)

Uses o1-10 and o1-11 to set the unit of measure. The value of parameter o1-10 is the value when you remove the decimal point from the maximum output frequency. Parameter o1-11 is to the number of digits after the decimal point in the maximum output frequency.

To display a maximum output frequency of 100.00, set parameters to these values:

  • o1-10 = 10000

  • o1-11 = 2 [User Units Decimal Position = 2 Dec (XXX.XX)]
