Connecting the control cables
I/O terminals
The figure below shows the I/O connectors.
The default connection of the control signals depends on the application macro in
use, which is selected with parameter 9902. See chapter Application macros for the
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 18 FREQ INPUT parameters
accordingly.
WARNING! All ELV (extra low voltage) 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.
