IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS!
This manual contains important instructions that should be followed during installation and maintenance
of the Servo Motor Controller (controller). The following are general safety precautions that are not related
to specific procedures and therefore do not appear elsewhere in this publication. These are recommended
precautions that personnel must understand and apply during many phases of maintenance.
The controller is electrically energized. Wherever electricity is present, there is the hazard of electrocution.
Like any other electrical device, the controller can be dangerous if it is improperly operated or maintained.
Safety Alert Symbols
Safety alert symbols are used in this manual to identify potential or immediate personal injury hazards. The
safety alert symbol words are explained below:
DANGERindicatesanimminentlyhazardoussituationwhich,ifnot
avoided, will result in injury or serious injury.
WARNINGindicatesapotentiallyhazardous situationwhich,ifnot
avoided, could result in injury or serious injury.
CAUTION indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
CAUTION used without the safety alert symbol indicates a poten-
tially hazardous situation which, if not avoided, may result in pro-
perty damage.
WEAR PROTECTIVE CLOTHING
!Wear protective clothing (gloves, apron, etc.) approved for the materials and tools being used.

USE APPROVED SAFETY EQUIPMENT
!When cleaners are being used, approved explosion-proof lights, blowers, and other equipment must
be used. Make sure that fire fighting equipment is readily available and in working order.
GIVE CLEANERS SPECIAL CARE
!Keep cleaners in special polyethylene bottles or in safety cans and in minimum quantities. Discard soil-
ed cleaning rags into safety cans.
Equipment Safety Information
The following safety information briefly discusses hazards peculiar to the equipment, which are likely to be
encountered during maintenance activity.
GENERAL OPERATING LOCATION PRECAUTIONS
!This manual covers equipment for use under the following atmospheric conditions:
CAn oxygen concentration not greater then 21 percent by volume
CA nominal barometric pressure of one atmosphere
!Use only authorized replacement parts or hardware.
!Observe proper Lock-Out/Tag-Out procedures when working on the controller and make sure that per-
sonnel protection equipment such as electrical grounds are installed.
!Make sure that all of the electrical wiring is properly terminated. Make sure that all of the wire terminals
are securely connected.
!Avoid hazardous voltage situations that can result from unsafe conditions such as, but not limited to
the following:
CImproper grounding
CHandling electrical leads or devices with wet hands or on wet ground
CDamaged electrical wire insulation
CImproper connection or re-connection of the power terminals.
CShort circuits to ground

DESCRIPTION AND OPERATION
1. Description
A. The Servo Motor Controller (see Figure 1) is installed remotely from the valve it controls, in its
own explosion proof container or in a separate customer furnished cabinet. In either case, the
controller must be located within 600 feet (182 meters) wire run length from the valve.
B. The controller consists of a servo amplifier, a position control I/O card and a power converter
packaged in a compact unit with readily accessible interface terminations. The servo amplifier
is pulse-width modulated.
C. The servo amplifier is mounted on a cold plate for improved heat conduction when enclosure
mounted.
2. Operation (Refer to Figure 2)
A. General
The controller is designed for control of high speed brushless DC servo motors for precision posi-
tioning of valves used on aero-derivative and frame DLE and SAC turbine engines.
B. Features
1) Speed and current control loops and many other functions, such as DC BUS status moni-
toring, softstart and recovery circuit management, and the protections thresholds detection,
carried out through numeric algorithms.
2) The digital mode allows a maximum stability related to the aging, the temperature and the
various application cases.
3) Settings are carried out through numbers calculated by means of analytic models and do
not depend upon analog calibrations.
C. Capabilities
1) Any 3-phase brushless DC motor can be driven by entering a set of parameters which
adjust the current loop and identify the motor’s electro-mechanical characteristics.
2) Any type of asynchronous motor can be very well driven by vector control, working as a
brushless servomotor, by entering the magnetization current (ID) and the slip gain (fre-
quency) additional parameters. Other parameters, used in connection with the hardware
features in common with brushless motors, remain active.

3) The motor transducer can be both a resolver (2 to 24 poles) and an incremental encoder
(1024 to 8192 pulses).
