Current per-unit input value
Display the current input value of the analog input in %.
NOTE
In the factory setting and after basic commissioning, an input current of 20 mA is
equal to the main setpoint 100 % reference speed (p2000), which has been set to
the maximum speed (p1082).
Example: Changing Analog Input 0 from Current to Voltage Input –10 to +10 V
S5.0 = "V"
p4056 = 4

F3505 – Fault: "Analog input cable breakage"
This fault is triggered when analog input type (p4056) is set to 3 (4 ... 20 mA with
open-circuit monitoring) and the input current of 2 mA has been undershot.
The fault value can be used to determine the analog input in question.

FaultValue: 0000000003 00000003(hex)
Cause:
TM31.Wire break analog input
