ABB TC520 3BSE001449R1 System Status Collector
Each input can be used with a current or voltage signal. The selection
is made with a DIP switch located behind the top lid of the NAIO
module casing (see Figure 3-1). The switch settings are shown below.
Figure 3-10 Analogue input type selection.
Note: Independent of the selection of the signal type, the values of the
analogue inputs are displayed in mA on the ACS 600 Control Panel;
e.g. 10 V will be displayed as 20 mA. This must be taken into account
when scaling the signals or reading the actual value of the analogue
inputs AI2 and AI3. See the drive manuals for more information.

0.5 to 1.5 mm2 twisted pair cables with individual and/or overall
screens should be used for analogue signals. The screens should be
connected to the SHF terminals on the NAIO module. See the example
below.
Note: X1 and X2 have separate RC filters as pictured above, i.e. the
SHF terminals on one terminal block are connected together, then to
earth through an RC filter.
Note: Do not route the signal cables parallel to power cables.
Programming The communication between the module and the drive is activated by a
drive parameter. (Ensure that the parameter settings correspond to the
mode switch setting of the module.) After activation, the NAIO replaces
certain standard inputs and outputs. See the drive Firmware Manual,
Parameter Group 98.
Users of Standard Application Program versions up to 3.0 should refer
to Appendix E for a listing of related drive parameters.
Note: The new settings take effect only the next time the module is
powered up.

Replacement
An NAIO-03 can be used to replace a faulty NAIO-01/02. For reference,
the differences of the NAIO types are detailed in Appendix E
