Switching between Main/Auxiliary Frequency References
To configure the frequency reference to switch between analog input A1 and A2
(main/aux frequency switch), use the following set up:
1. Set the frequency reference source to terminals (b1-01 = “1”).
2. Set one of the digital inputs to auxiliary reference 1 (H1-®® = “3” (preset for
terminal S5).
3. Set input signal type of terminal A2 using dip switch S1 and parameter H3-09.
4. Set the function of analog input A2 to Auxiliary frequency (H3-10 = “3”).
When the digital input assigned in step 2 is off, terminal A1 is the frequency
reference input. If it is closed, the A2 input value becomes the frequency reference.
The active acceleration / deceleration times are used for the change-over between
the values
