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.
Fig 6.35 Jump Frequency Setting Using an Analog Input
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.
Related Parameters
The block diagram in Fig 6.36 explains the functioning of the pulse train input.
Fig 6.36 Frequency Reference Adjustments Using Pulse Train Inputs
The principle for setting the input gain and bias is the same as for the analog inputs (refer page 6-26 pp). The
only difference is that the input signal is not a voltage or a current but a pulse train.
