If a parameter needs to be displayed during the running, set the corresponding
bit to 1, and set b9-04 to the hexadecimal equivalent of this binary number.
b9-05
Load speed display coefficient
Default
1.0000
Setting Range
0.0001~ 6.5000
This parameter is used to adjust the relationship between the output frequency of frequency inverter and the load
speed. For details, see the description of b9-06.
b9-06
Number of decimal places for load speed display
Default
1
Setting
Range
0
0 decimal display
1
1 decimal display
2
2 decimal display
3
3 decimal display
b9-06 is used to set the number of decimal places for load speed display. The followinggives an example to explain
how to calculate the load speed:
Assume that b9-05 (Load speed display coefficient) is 2.000 and b9-06 is 2 (2 decimalplaces). When the running
frequency of the frequency inverter is 40.00 Hz, the load speed is 40.00 x2.000 = 80.00 (display of 2 decimal places).
If the frequency inverter is in the stop state, the load speed is the speed corresponding to the set frequency, namely,
"setting load speed". If the set frequency is 50.00 Hz, the load speed in the stop state is 50.00 x 2.000 = 100.00
