Using an External +5V Logic Supply
When using an external +5V dc power supply with your Ultra3000
(2098-DSD-005, -010, and -020), the +5V dc must not be grounded
inside the supply, since it will be referenced to the drive common.
External +5V dc power supply connections should be made to CN1-2
and CN1-3.
The following table provides a description of the requirements for an
external +5V dc power supply used to power the logic.
Digital Inputs
There are eight opto-isolated digital inputs. All digital inputs (SERCOS
and non-SERCOS) have the same configuration, as shown in the figure
below.

Digital Input Circuit
IMPORTANT
Using the drive-mounted breakout board with 24V to
5V auxiliary power converter is preferred to using an
external +5V dc power supply.
