Connecting the control cables
I/O terminals
The figure below shows the I/O connectors. Tightening torque is 0.5 N·m / 4.4 lbf. in.
Default connection
The default connection of the control signals depends on the application macro in
use, which is selected with parameter
. See chapter
for the
connection diagrams.
Voltage and current selection
Switch S1 selects voltage (0 (2)…10 V / -10…10 V) or current (0 (4)…20 mA /
-20…20 mA) as the signal types for analog inputs AI1 and AI2. The factory settings
are unipolar voltage for AI1 (0 (2)…10 V) and unipolar current for AI2
(0 (4)…20 mA), which correspond to the default usage in the application macros.
Voltage and current connection
Bipolar voltage (-10…10 V) and current (-20…20 mA) are also possible. If a bipolar
connection is used instead of a unipolar one, see section
on page
for how to set parameters accordingly.
Frequency input
If DI5 is used as a frequency input, see section
for how
to set parameters accordingly.
