Configuration of standard analog inputs.Standard AI12
No action / uint16Triggers the analog input tuning function.
Connect the signal to the input and select the appropriate
tuning function.
AI tune12.1
0AI tune is not activated.No action
1Current analog input AI1 signal value is set as minimum
value of AI1 into parameter 12.17 AI1 min. The value
reverts back to No action automatically.
AI1 min tune
2Current analog input AI1 signal value is set as maximum
value of AI1 into parameter 12.18 AI1 max. The value
reverts back to No action automatically.
AI1 max tune
3Current analog input AI2 signal value is set as minimum
value of AI2 into parameter 12.27 AI2 min. The value
reverts back to No action automatically.
AI2 min tune
4Current analog input AI2 signal value is set as maximum
value of AI2 into parameter 12.28 AI2 max. The value
reverts back to No action automatically.
AI2 max tune
No action / uint16Selects how the drive reacts when an analog input signal
moves out of the minimum and/or maximum limits specified
for the input.
AI supervision
function
12.3
The supervision applies a margin of 0.5 V or 1.0 mA to the
limits. For example, if the maximum limit for the input is
7.000 V, the maximum limit supervision activates at 7.500
V.
The inputs and the limits to be observed are selected by
parameter 12.4 AI supervision selection.
Note: Analog input signal supervision is only active when
• the analog input is set as the source (using the AI1
scaled or AI2 scaled selection) in parameter 22.11,
22.12, 22.15, 22.17, 23.42, 26.11, 26.12, 26.16,
26.25, 28.11, 28.12, 30.21, 30.22, 40.16, 40.17,
40.50, 41.16, 41.17, 41.50 or 44.9, and is being used
as the active source, or
•
supervision is forced using parameter 12.5 AI
supervision force.

1
Drive trips on 80A0 AI Supervision.
Fault
2
Drive generates an A8A0 AI Supervised Warning warning.
Warning
3
Drive generates a warning (A8A0 AI Supervised Warning)
and freezes the speed (or frequency) to the level the drive
Last speed
was operating at. The speed/frequency is determined on
the basis of actual speed using 850 ms low-pass filtering.
WARNING!
Make sure that it is safe to continue operation in
case of a communication break.
