Chapter 2: Introduction
This installation guide describes the Duo and the steps for its wiring, installation and
power-up. Following these guidelines ensures maximum functionality of the product and
the system to which it is connected.

2.1 Product Description

The Duo series of servo drives enhances Elmo’s range of digital servo drives, recognized
for having the highest power density and intelligence. The Duo is a highly compact
integrated solution containing two drives in a single package. The solution operates
under a single power supply and is designed for applications with up to two axes.
The Duo integrates Elmo’s advanced “Elmo First Control” technology, which contributes
to the product’s excellent control performance, wide range of functionalities and high
efficiency and reliability. The solution includes two fully separated digital motion
controllers that feature:
CANopen-based networking operating simultaneously via RS-232 and CANopen
DS 301, DSP 305, DSP 402 communications and featuring a third-generation
programming environment
Current, velocity and position control loops including PT and PVT
Commutation types
Position feedbacks
The benefits are high dynamics and increased precision for dual axis automated
machines such as robots, feeders, up- and down-loaders, conveyor belts and production
lines.
Power to the various Duo models is provided by a 0 - 95VDC source. A “smart” control-
supply algorithm enables the Duo to operate with only one power supply and there is no
need for an auxiliary power supply for the logic.
If back-up functionality is required for storing control parameters in case of power-loss,
an external 12 ~ 95VDC supply should be connected (via the +VL terminal on the Duo)
providing maximum flexibility and backup functionality when needed.
Note: This back-up power supply can operate from any voltage source within the
12 ~ 95VDC range. This is much more flexible than a standard 24VDC power supply
requirement.
The Duo series fully complies with all relevant safety and EMC regulations.
