u Input Signal Selection for Terminals A1 and A2
Terminals A1 and A2 can be used to input either a voltage or a current signal. Select the signal type using jumper S1 as
explained in Table 3.10 . Set parameters H3-01 and H3-09 accordingly as shown in Table 3.11 .
Note: If terminals A1 and A2 are both set for frequency bias (H3-02 = 0 and H3-10 = 0), both input values will be combined to create the frequency
reference.
