5.3.9 DOH frequency multiplication coefficient
• This parameter is used to set the output square-wave characteristic of output terminal DOH.
DOH frequency multiplication coefficient
•
When 02-43 is set to 1~9000, the external terminal DOH select the frequency multiplication output function which
maximum frequency is 100 kHz.
•
When 02-43 is set at 5 and the instantaneous frequency of operation is 20Hz, the output pulse wave between ter-
minal DOH and terminal D-C is as following diagram:
ote:
N
When 02-43=1, the output is one time of the running frequency. And the inverter can provide the output from 1~650Hz which
precision is 1%. The bigger the value of 02-43 and the bigger the running frequency is, the worse the precision will be.
