Setting Jump Frequency Reference Using an Analog Input
When parameter H3-09 (analog input A2 function selection) is set to A (jump frequency), the jump frequency
can be changed by the terminal A2 input value (respectively H3-05 and channel 3 of the AI-14B option card).
Setting Precautions
Set the jump frequencies according to the following formula: d3-01 ≥ d3-02 ≥ d3-03 > Analog input.
•
When parameters d3-01 to d3-03 are set to 0 Hz, the jump frequency function is disabled.
•
Adjusting Pulse Train Input Reference Values
If b1-01 is set to 4 and H6-01 is set to 0, the pulse train input is selected as the frequency reference source. Set
the pulse frequency that is equal to 100% reference in parameter H6-02, and then adjust the gain and bias
accordingly using H6-03 and H6-04.
