MAN-GUIIG (V er. 1.601)
Guitar Installation GuideSafety Information
1.1. Warnings
• To avoid electric arcing and hazards to personnel and electrical contacts, never
connect/disconnect the servo drive while the power source is on.
• Power cables can carry a high voltage, even when the motor is not in motion. Disconnect
the Guitar from all voltage sources before it is opened for servicing.
• The Guitar servo drive contains grounding conduits for electric current protection. Any
disruption to these conduits may cause the instrument to become hot (live) and dangerous.
• After shutting off the power and removing the power source from your equipment, wait at
least 1 minute before touching or disconnecting parts of the equipment that are normally
loaded with electrical charges (such as capacitors or contacts). Measuring the electrical
contact points with a meter, before touching the equipment, is recommended.
1.2. Cautions
• The Guitar servo drive contains hot surfaces and electrically-charged components during
operation.
9
• The maximum DC power supply connected to the instrument must comply with the
parameters outlined in this guide.
• When connecting the Guitar to an approved auxiliary power supply, connect it through a
line that is separated from hazardous live voltages using reinforced or double insulation in
accordance with approved safety standards.
• Before switching on the Guitar, verify that all safety precautions have been observed and
that the installation procedures in this manual have been followed.
• Do not clean any of the Guitar drive's soldering with solvent cleaning fluids of pH greater
than 7 (8 to 14). The solvent corrodes the plastic cover causing cracks and eventual damage
to the drive's PCBs.
Elmo recommends using the cleaning fluid Vigon-EFM which is pH Neutral (7).

Chapter 2: Introduction
Guitar Installation Guide
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 8.0 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.
11
The Guitar servo 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
programmable with the Elmo Composer motion control language.
Power to the Guitar is provided by an isolated DC power source (not included with the Guitar). A
“smart” control-supply algorithm enables the Guitar to operate with only this 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 isolated supply should be connected (via the VL terminal on the Guitar) providing
maximum flexibility and backup functionality when needed.
If backup power is not needed, two terminals (VP and VL) must be connected together by the
user. 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 CAN DS
301, DS 305, DS 402 communications and features a third-generation programming
environment.
SimplIQ product line, is fully
• The Advanced Guitar includes all the motion capabilities and communication options
included in the Standard model, as well as advanced positioning capabilities: ECAM, Dual
Loop and increased program size.
Both versions operate with RS-232 and CAN communication.

3.3.3. Connector J2
Connector J2: Communications, Auxiliary Feedback and I/O functions
The Guitar was designed for mounting on a printed circuit board (PCB) via 2 mm pitch 0.51 mm
square pins. When integrating the Guitar into a device, be sure to leave about 1 cm (0.4")
outward from the heatsink to enable free air convection around the drive. We recommend that
the Guitar be soldered directly to the board. Alternatively, though this is not recommended,
the Guitar can be attached to socket connectors mounted on the PCB. If the PCB is enclosed in
a metal chassis, we recommend that the Guitar be screw-mounted to it as well to help with
heat dissipation. The Guitar has screw-mount holes on each corner of the heatsink for this
purpose.
20
Figure 3: The Guitar Footprint
When the Guitar is not connected to a metal chassis, the application’s thermal profile may
require a solution for heat dissipation due to insufficient air convection. In this case, we
recommend that you connect an external heatsink.

Guitar Installation GuideInstallation
3.5. Integrating the Guitar on a PCB
The Guitar is designed to be mounted on a PCB, either by soldering its pins directly to the PCB
or by using suitable socket connectors. In both cases the following rules apply:
3.5.1. Traces
1. The size of the traces on the PCB (thickness and width) is determined by the current
carrying capacity required by the application.
The rated continuous current limit (Ic)of the Guitar is the current used for sizing the
motor traces (M1, M2, M3 and PE) and power traces (VP+, PR and PE).
For control, feedbacks and Inputs/ outputs conductors the actual current is very small
but “generous” thickness and width of the conductors will contribute to a better
performance and lower interferences.
2. The traces should be as short as possible to minimize EMI and to minimize the heat
generated by the conductors.
3. The spacing between the high voltage conductors (VP+, PR, M1, M2, M3, VL) must be at
least:
21
Surface layer: 1.5 mm
Internal layer: 0.5 mm
Complying with the rules above will help satisfy UL safety standards, MIL-STD-275 and the
IPC-D-275 standard for non-coated conductors, operating at voltages lower than 200 VDC.
3.5.2. Grounds and Returns
The “Returns” of the Guitar are structured internally in a star configuration. The returns in each
functional block are listed below:
Functional Block Return Pin
Power PR (Power Return)
Internal Switch Mode P. S. PR (Power Return)
RS-232 Communications RS232_COMRET (J1/3)
CAN Communications CAN_COMRET (J1/30)
Control section COMRET (J1/28)
Main Feedback SUPRET (J2/2)
Aux. Feedback SUPRET (J1/6)
Analog input ANLRET (J2/2)
www.elmomc.com
MAN-GUIIG (V er. 1.601)
Guitar Installation GuideInstallation
The returns above are all shorted within the Guitar in a topology that results in optimum
performance.
1. When wiring the traces of the above functions, on the Integration Board, the Returns of
each function must be wired separately to its designated terminal on the Guitar. DO NOT USE A COMMON GROUND PLANE. Shorting the commons on the Integration Board may
cause performance degradation (ground loops, etc).
2. Inputs: The 6 inputs are optically isolated from the other parts of the Guitar. Each input has
a separate floating return (INRET1 for input 1 and INRET2 for input 2, etc.). To retain
isolation, the Input Return pins, as well as other conductors on the input circuit, must be
laid out separately.
3. Outputs: The 4 outputs are optically isolated from the other parts of the Guitar. Each
output has a separate floating return (OUTRET1 for output 1 and OUTRET2 for output 2,
etc.) To retain isolation, the Output Return pins, as well as other conductors on the output
circuit, must be laid out separately.
4. Return Traces: The return traces should be as large as possible, but without shorting each
other, and with minimal cross-overs.
22
5. Main Power Supply and Motor Traces: The power traces must be kept as far away as
possible from the feedback, control and communication traces.
6. PE Terminal: The PE terminal is connected directly to the Guitar’s heat-sink. The heat-sink
serves as an EMI common plane. The PE terminal should be connected to the system's
Protective Earth. Any other metallic parts (such as the chassis) of the assembly should be
connected to the Protective Earth as well.
7. Under normal operating conditions, the PE trace carries no current. The only time these
traces carry current is under abnormal conditions (such as when the device has become a
potential shock or fire hazard while conducting external EMI interferences directly to
ground). When connected properly the PE trace prevents these hazards from affecting the
drive.
Caution:
Follow these instructions to ensure safe and proper implementation. Failure to
meet any of the above-mentioned requirements can result in
drive/controller/host failure.
