5.2.2.2 DIP switch configuration of the inverter
The analog inputs in the frequency inverter are suitable for current and voltage setpoints. For correct
processing of current setpoints (0-20mA / 4-20mA) the relevant DIP switch (S1) must be set for current
signals ("ON").
Adjustment to fail-safe signals in case of cable breaks (2-10V/4-20mA) is made via parameters 402 and 403.
A second DIP switch (S2) is also available, via which the system bus address can be specified or the
system bus can be activated. This has priority over the parameters P509, P514 and P515.
