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
Table 6-5 Example: setting analog input 0
Current / voltage switchover
Set current/voltage selector to "Voltage" ("V").
Set analog input type 0 to -10 V... +10 V.
Note
The new analog input must then be stored on the CompactFlash card so that it is protected
in the event of a power failure.
F3505 – Fault: "Analog input, wire breakage"
The 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.
