Offset adjustment within the analog input link
Set 16 Bit application parameter as target for the analog input link.
Example: Target parameter = P3333
Read the value in ProDrive while input is open (0 mA).
Example: -179 increments
Offset adjustment:
Example offset adjustment =
⇒ value to be set: 0.273 %.
Gain adjustment within the analog input link
Connection 10 mA
Measured current (amperemeter): 10.000 mA
