BIPOLAR ANALOG OUTPUT

4.3.4 Terminal DA1 response level adjustment (Pr. 839)

⋅

The response level of the output voltage of the terminal DA1 can be adjusted between 0 and 5s with 

Pr. 

839

.

⋅

Increasing the setting stabilizes the terminal DA1 output more but reduces the response level.

REMARKS

⋅

Response time of the terminal DA1 is a total of the set value in

 Pr.839 DA1 output filter

 and a variable (up to 5ms).
