4 – Jumpers position
Check the positions of jumpers J1 and J2 on the control unit of the drive.
These jumpers determine whether analog inputs AI1 and AI2 are current or voltage.
Check/adjust the following parameters.
Select the unit to either mA or V,
corresponding to jumper J1 setting.
12.15 AI1 unit selection
Configure analog inputs if used for drive
control:
Parameters
12.17 and 12.18 – set the low
and high limits of the analog input signal.
Scaling parameters
12.19 and 12.20 – define
the internal signal levels that correspond to
the low and high limits. See graph below.
The corresponding parameters for analog
input AI2 are
12.27 … 12.30 .
