Function disabled if analog scaling block programmed to output negative setpoints (see P0757 to P0760).
Dependency:
When monitoring is enabled and a deadband defined (P0761), a fault condition will be generated (F80) if
Notice:
the analog input voltage falls below 50 % of the deadband voltage. It is not possible to select the bipolar
voltage for analog input 2.
See P0757 to P0760 (analog input scaling).
Note:
In current mode, if the input exceeds 24mA, the inverter will trip F80/11 for analog input 1 and F80/12 for
analog input 2. This will result in channel switching back to voltage mode. Analog input parameter read-
ings for the channel concerned will no longer be updated until the fault (F80) has been reset. Once the
fault has been reset then the input will switch back to current mode and normal readings will resume.

scaling
P0757 - P0760 configure the input scaling. x1 is the first value of the two pairs of variants x1 / y1 and x2 /
y2 which determine the straight line. The value x2 of analog input scaling P0759 must be greater than the
value x1 of analog input scaling P0757.
See r0752
Index:
Analog setpoints represent a [%] of the normalized frequency in P2000.
Notice: •
Analog setpoints may be larger than 100 %.
•
ASPmax represents highest analog setpoint (this may be at 10 V or 20 mA).
•
ASPmin represents lowest analog setpoint (this may be at 0 V or 20 mA).
•
Default values provide a scaling of 0 V or 0 mA = 0 %, and 10 V or 20 mA = 100 %.
