Explanation of the parameters
Parameters
P111 AI1 Offset
Unit: [mV]
Setting range: –500 ... 0 ... 500 mV
When the setpoint is selected by an external controller, it is possible to compensate for
a voltage offset present at analog input AI1 when the setpoint selection is zero. The set-
ting of this parameter causes calibration of the coordinate basic origin of Figure 26. This
setting takes effect in all AI1 operating modes.
P112 AI1 Opera-
ting mode
The selection for the AI1 operating mode differentiates between various characteristic
curves and voltage/current input.

Ref. N-MAX: Voltage input with reference n
max
(P302 Maximum speed 1 / P312 Max-
imum speed 2). Clicking on P110 AI1 Scaling you can adapt the characteristic curve.
P113 AI1 voltage offset and P114 AI1 speed offset will have no effect.
•
Reference 3000 1/min: Voltage input with reference 3000 1/min. Clicking on P110
AI1 Scaling you can adapt the characteristic curve. P113 AI1 voltage offset and P114
AI1 speed offset will have no effect.

. Clicking on P113 AI1 voltage offset
you can adapt the characteristic curve. P110 AI1 Scaling and P114 AI1 speed offset
will have no effect.
•
N-Off., N-MAX Voltage input with reference n
max
. Clicking on P114 AI1 speed offset
you can adapt the characteristic curve. P110 AI1 Scaling and P113 AI1 voltage offset
will have no effect.

N-MAX, 0-20mA: Current input 0 ... 20 mA = 0 ... n
max
, no setting options (P110 AI1
Scaling has no effect). Set the internal burden (250
Ω
) "S11 = ON."
•
N-MAX, 4-20mA: Current input 4 ... 20 mA = 0 ... n
max
, no setting options (P110 AI1
Scaling has no effect). Set the internal burden (250
Ω
) "S11 = ON."
