4.7 Basic parameterization of the drive objects
4. Repeat the password in the "Confirm password" field.
For security reasons, the password entries displayed in the input fields are encrypted.
The entry is checked. If the entry is correct, the message "Password has been changed"
is displayed.
5. Then save the project to accept the settings.

Configuring inputs/outputs of the Control Unit

Isolated digital inputs
You can change the interconnection of the digital inputs 0 ... 7, 16, 17 and 20, 21 on the
CU320-2 Control Unit in the "Isolated digital inputs" mask.
● Digital inputs are used for the acquisition of digital signals. For example, drive enables
can be controlled externally. The interconnection of digital inputs is made via BICO
interconnections.
● For every digital input signal there is the corresponding inverted signal which can also be
used for interconnection.
Simulation mode
The selection box for the terminal evaluation / simulation switchover is only visible online.
Interconnecting digital inputs 0 ... 7, 16, 17 and 20, 21 (r0722 and r0723)
1. Interconnect the signal sources of the digital inputs 0 ... 7, 16, 17 and 20, 21.
Several interconnections are possible.
Bidirectional digital inputs/outputs
The bidirectional inputs/outputs of terminals X122 and X132 on the CU (DO1) can be used
by a drive object as well as by a higher-level controller (resource sharing). The assignment
to a terminal is defined by means of BICO interconnections which are either connected to a
controller via the DO1 telegram p0922 = 39x or to a drive object.
You can change the interconnection of the bidirectional digital inputs/outputs on the
input/output component.
● You can assign bidirectional digital inputs/outputs in the function. This means they can be
parameterized either as an input or an output.
● Digital inputs are used for the acquisition of digital signals. For example, drive enables
can be controlled externally.
● For every digital input signal there is the corresponding inverted signal which can also be
used for interconnection.
● Digital outputs are used for the feedback of signals such as enables.
