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

6.5.2 Motorized potentiometer
Description
The digital motorized potentiometer enables you to set speeds remotely using switching
signals (+/- keys). It is activated via terminals or fieldbus. As long as a logical 1 is present at
signal input "MOP raise" (setpoint higher), the internal numerator integrates the setpoint. You
can set the integration time (time taken for the setpoint to increase) using parameter p1047.
In the same way, you can decrease the setpoint using signal input "MOP lower". The
deceleration ramp can be set using parameter p1048.
Configuration parameter p1030.0 = 1 (default setting = 0) enables non-volatile storage of the
current motorized potentiometer value when powering down the drive unit. When powering-
up the drive unit, the starting (initial) value of the motorized potentiometer is set to the last,
actual value that was present when the drive unit was powered-down.
Precondition
The default setting for the motorized potentiometer was chosen during commissioning:
• STARTER (p1000):
"Motorized potentiometer"
• AOP30 (p1000):
"3: Motorized potentiometer"
