Description
The drive generates an AI SUPERVISION alarm and sets the
speed to the speed defined by parameter
safe.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
The drive generates an AI SUPERVISION alarm 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.
Selects the analogue input signal supervision limit.
Action selected by parameter
AI1 signal value falls below the value defined by equation: par.
AI1 min - 0.5 mA or V
AI1 signal value exceeds the value defined by equation: par.
