Chapter 2: Introduction

This installation guide describes the Guitar servo drive and the steps for its wiring,

installation and power-up. Following these guidelines ensures maximum functionality of

the drive and the system to which it is connected.

2.1 Drive Description

The Guitar series of digital servo drives is designed to deliver “the highest density of

power and intelligence”. The Guitar delivers up to 4.8 kW of continuous power or

5.4 kW of peak power in a 119. 6 cc (6.95 in³) package (80 x 24.5 x 61 mm or 3.15" x 0.965"

x 2.4").

The Guitar is designed for OEMs. It operates from a DC power source in current, velocity,

position and advanced position modes, in conjunction with a permanent-magnet

synchronous brushless motor, DC brush motor, linear motor or voice coil. It is designed for

use with any type of sinusoidal and trapezoidal commutation, with vector control. The

Guitar can operate as a stand-alone device or as part of a multi-axis system in a distributed

configuration on a real-time network.

The Guitar drive 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 drive

for optimal use with their motor. The Guitar, as part of the

SimplIQ product line, is fully

programmable with the Elmo Metronome motion control language.

Power to the Guitar is provided by a 12 ~ 195 VDC isolated DC power source (not included

with the Guitar). A “smart” control-supply algorithm enables the Guitar to operate with

only one power supply with no need for an auxiliary power supply for the logic.

If backup functionality is required for storing control parameters in case of power-loss, an

external 12 ~ 195 VDC isolated supply should be connected (via the +VL terminal on the

Guitar) providing maximum flexibility and backup functionality when needed.

Note: This backup power supply can operate from any voltage source within the 12 ~ 195

VDC range. This is much more flexible than a standard 24 VDC power supply requirement.

If back-up power is not needed, two terminals (VP and VL) are shorted so that the main

power supply will also power the control/logic supply. In this way there is no need for a

separate control/logic supply.

The Guitar is a PCB mounted device which enables efficient and economic implementation.

The Guitar is available in two models:

 The Standard Guitar is a basic servo drive which operates in current, velocity and

position modes including Follower and PT & PVT. It operates simultaneously via RS-

232 and CANopen DS 301, DS 305, DS 402 communications and features a third-

generation programming environment.
