Terminal A2 Switch

The main frequency reference can either be a voltage or current signal input. For voltage
signals both analog inputs, A1 and A2, can be used, for current signals A2 must be used.
To use current input at terminal A2, set the DIP switch S1 to "I" (factory setting) and set
parameter H3-09 = "2" or "3" (4-20 mA or 0-20 mA). Set parameter
H3-10 = "0" (frequency reference).
Note: If Terminals A1 and A2 are both set for frequency reference (H3-02 = 0
and H3-10 = 0), the addition of both input values builds the frequency reference.
When using input A2 as voltage input, set the DIP switch S1 to "V" (left position) and
program parameter H3-09 to "0" (0 to +10 Vdc with lower limit) or "1" (0 to +10 Vdc
without lower limit).
