Connecting the control cables

I/O terminals
The figure below shows the I/O connectors.
S1
The default connection of the control signals depends on the application macro in
use, which is selected with parameter 9902. See chapter
connection diagrams.
Switch S1 selects voltage (0 (2)...10 V) or current (0 (4)...20 mA) as the signal type
for analog input AI. By default, switch S1 is in the current position.
If DI5 is used as a frequency input, set group
accordingly.
WARNING! All ELV circuits connected to the drive must be used within a zone of
equipotential bonding, i.e. within a zone where all simultaneously accessible
conductive parts are electrically connected to prevent hazardous voltages appearing
between them. This is accomplished by a proper factory grounding.
