Appendix 6 Frequency parameters of ultra-high-speed
Frequency parameters
1.
After setting the inverter ultra high-speed operation function parameter P.187, please be sure to
set P.998 to adjust the frequency-dependent parameters.
2.
In the use of inverter ultra-high-speed operation function, do not use PU series operation panels
to achieve parameter copy function by set P.994 and P.995.
3.
Inverter ultra-high speed operation function, by the use of communication written in frequency,
please pay attention to the size of the set value. Because if P.187 = 1, minimum setting unit is 0.1
Hz.
For example: Change value of P.195 to 50 (initial value is 60) in communication example 4.
Step1 and step 2 are the same as step1 and step2 of example 3.
Step 3. The PC requests the inverter to inputting 50 into P.195, using the format A:

195 minus 100 equal to 95, then
Minimum unit of P.195 is 0.1, therefore
converting 95 to hexadecimal H5F, 50*10=500, then convert 500 to
H5F+H80=HDF. Hexadecimal H01F4, and convert 0,1,F,4
to ASCII CODE to send out.
4.
On the ultra-high-speed operation function, the can not use the sensor vector speed control
function.
