Overview The NTAC-01 is compatible with ACS 600 drives with Standard
Application Program versions from 2.8 to 3.0. Version 5.0 (and later)
require the use of the NTAC-02. Thus, NTAC-01 and NTAC-02 are not
interchangeable.
Differences between
NTAC-01 and NTAC-02
All information about the NTAC-02 given elsewhere in this manual also
applies to the NTAC-01, with the exception of what is listed in this
section.
Terminal Designations The terminals of the NTAC-01 can be connected as shown for the
NTAC-02 in Chapter 3. Although unmarked on the label, NTAC-01
terminal X2:1 can actually be used as an additional -V terminal.
Moreover, the SH and PE terminals are both connected to module
earth.
Encoder Supply Voltage The encoder supply voltages available from the NTAC-01 are 12 and
24 V (instead of 15 and 24 V available with the NTAC-02).
Cabling The maximum encoder cable length for the NTAC-01 is 150 m.
Technical Data Encoder inputs:
• Logical thresholds (12 V encoder supply): “1” > 8.3 V, “0” < 3.7 V

Application Program
V2.8 to 3.0
This section only applies when an NTAC-01 module is connected to an
ACS 600 equipped with Standard Application Program version 2.8 to
3.0. Users of other application programs should refer to the drive
manuals.
Before adjusting the parameters, ensure that the module node number
is set to 16. Note that the setting takes effect only on the following
module power-up.
98.1 ENCODER
MODULE
This parameter activates the communication between the ACS 600 and
the NTAC module.
YES
Communication is active.
NO
Communication is not active.
