3.7 Main Frequency Reference
u DIP Switch S1 Analog Input Signal Selection
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.
When using input A2 as a voltage input, set 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).
To use current input at terminal A2, set the DIP switch S1 to "I" (default 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.
