Control Circuit Terminal A2 (Voltage/Current Input):
Use control circuit Terminal A2 when supplying the frequency reference with a current signal
between 4 to 20 mA. Use the following switch and parameter settings to configure Terminal
A2 for 0 to 20 mA or 4 to 20 mA input.
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 setup:
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 = “2”).
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
