Parameters and firmware blocks
136
(3) AI2 min tune Current analogue input AI2 signal value is set as minimum value for
AI2, parameter 13.08 AI2 MIN. The value reverts back to (0) No action
automatically.
(4) AI2 max tune Current analogue input AI2 signal value is set as maximum value for
AI2, parameter 13.07 AI2 MAX. The value reverts back to (0) No
action automatically.
13.12 AI SUPERVISION FW block: None
Selects how the drive reacts when analogue input signal limit is reached. The limit is selected by
parameter 13.13 AI SUPERVIS ACT.
(0) No No action taken.
(1) Fault The drive trips on fault AI SUPERVISION.
(2) Spd ref Safe The drive generates alarm AI SUPERVISION and sets the speed to
the speed defined by parameter 46.02 SPEED REF SAFE.
WARNING! Make sure that it is safe to continue operation in
case of a communication break.
(3) Last speed The drive generates alarm AI SUPERVISION and freezes the speed
to the level the drive was operating at. The speed is determined by the
average speed over the previous 10 seconds.
WARNING! Make sure that it is safe to continue operation in
case of a communication break.
13.13 AI SUPERVIS ACT FW block: None
Selects the analogue input signal supervision limit.
Example: If parameter value is set to 0010 (bin), bit 1 AI1>max is selected.
0b0000…0b1111 AI1/AI2 signal supervision selection.
Bit Supervision selected by parameter 13.12 AI SUPERVISION is activated if
0 AI1<min AI1 signal value falls below the value defined by equation:
par. 13.03 AI1 MIN - 0.5 mA or V
1 AI1>max AI1 signal value exceeds the value defined by equation:
par. 13.02 AI1 MAX + 0.5 mA or V
2 AI2<min AI2 signal value falls below the value defined by equation:
par. 13.08 AI2 MIN - 0.5 mA or V
3 AI2>max AI2 signal value exceeds the value defined by equation:
par. 13.07 AI2 MAX + 0.5 mA or V
