ElmoMC SimplIQ Digital Servo Drives-Whi-Trio Installation Guide - Manual (Page 9)

Introduction
This installation guide describes the Trio 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.
.1 Product Description
The Trio was designed to be a very compact product oriented for X, Y, Z applications
integrating three servo drives in one package and working under one power supply equipped
by a built-in shunt regulator. It is provided with standard terminal blocks for power
connections, and header sockets for signal connections.
It operates from an AC/DC power source in current, velocity, position and advanced position
modes, in conjunction with permanent-magnet synchronous brushless motors, DC brush motors,
linear motors or voice coils. The Trio is designed for use with any type of sinusoidal and
trapezoidal commutation, with vector control.
The Trio is easily set up and tuned using Elmo’s Composer software tools. This Windows-based
application enables users to quickly and simply configure the servo drives for optimal use with
their motor. The Trio, as part of the SimplIQ product line, is fully programmable with the Elmo
Composer motion control language.
Power to the Trio is provided by a 8.5 ~ 62 VAC isolated AC power source (not included with the
Trio). A “smart” control-supply algorithm at each Whistle enables the Trio to operate with only
one power supply with no need for an auxiliary power supply for the logic.
Optional power to the Trio is by providing a 12 ~ 88VDC isolated DC power source (not included
with the Trio).
If back-up functionality is required for storing control parameters in case of power-loss, an
external 12 ~ 95 VDC supply should be connected (via the +VL terminal on the Trio) providing
maximum flexibility and backup functionality when needed.
Note: This back-up power supply can operate from any voltage source within the 12 ~ 95 VDC
range. This is much more flexible than a standard 24VDC power supply requirement.
The Trio has an integrated shunt regulator, designed for use with high-inertia loads.
The Trio is a basic three servo drives which operate individually in current, velocity and a
position mode includes PT & PVT. It operates simultaneously via RS-232 and CANopen DS
301, DS 305, DS 402 communications and features a third-generation programming
environment.
The Trio series fully complies with all relevant safety and EMC regulations.
