ABB DSQC352 Robot Control Unit
Location
The fieldbus adapter is DIN rail-mounted inside the
control compartment (3-8).
The indicated mounting position may vary depending on the number of optional devices on the swing
frame.
3.3.6 Pulse encoder interface NTAC (option)
Overview
In the following cases, a speed encoder is needed:
• If an immediate fly-start is required and there is
no time to scan the speed.
• If the application requires a speed accuracy of
0.5% of the nominal speed or better.
• If operation below 10% nominal speed is continuous, which means more than a few seconds.
• If it is a master/follower application with
mechanically coupled machines.
In any other case, including constant torque applications, an encoder is not required..
Communication with AMC circuit board
The NTAC module communicates with the AMC circuit board of the INU via a fast optical link using
the standard DDCS protocol. The optical fibers are
connected to channel 1 of the AMC circuit board.
Location
The NTAC interface is DIN rail-mounted inside the
control compartment (3-8).
The indicated mounting position may vary depending on the number of optional devices on the swing
frame.
3.3.7 Motor temperature supervision
Motor temperature supervision is accomplished
via optional PT100 input modules. These modules
are suitable for connection of PT100 resistance
thermometers in accordance with IEC60751 in 2, 3
or 4 conductor systems.

The drive must only be handled by personnel who are skilled and
experienced in unpacking and transporting heavy equipment.
4.2 Transport conditions
Transformer, Converter and Fans are considered separate
transport sections.
The transport conditions for the drive are based on
IEC 60721-3-2 'Classification of environmental con ditions: Classification of groups of environmental
parameters and their severities; Transportation'.
