Mcs-Plus-gb Ver.21/02/2002
The MICROSPEED PLUS series of amplifiers are marked CE
because they conform to European Directives for
Electromagnetic Compatibility and Low Voltage.
This manual describes the mechanical and electrical
characteristics of the Microspeed Plus servoamplifier series.
It is important that the installation procedures are only
performed by qualified personnel in accordance with local
safety guidelines.
Whoever installs the equipment must follow all of the
technical instructions printed in this manual.

Danger Sign
This symbol is used where security directives should
be adhered to, where substantial risks are involved, and
where life endangerement or injury could occur.
Installers must scrupulously adhere to
prescribed directives and must communicate
them to the users.
Warning of Current being present
This symbol warns the user/installer to pay particular
attention to the presence of dangerous voltage (up to
270Vdc).
It's recommended to always remove drive from the
power supply net before working on the drive.
Warning
This symbol is present in all particularly important
points.
It's used where the intent is to highlight useful
considerations, prescriptions, indications, and the
correct execution procedures of every type of
intervention and prevention of damaging both systems
and drives.
General Security Directives
Along with what is prescribed in the manual, pay
attention to the security directives for prevention
of accidents and risks.
Always remove the power supply (disable) from both
the system and the drive prior to any type of intervention
on electric or mechanical parts.

Service Manual
Plus
MICROSPEED
The Microspeed Plus must only be installed by trained, qualified
and authorized personnel.
Any intervention or modifications effected on Microspeed Plus,
and their components or accessories, constitutes loss of
guarantee.
Isolate the drive from the power supply net before removing it
(by removing fuses or turning off the principal power switch).
The drive is equipped with electronic protections that disactivate
it in case of abnormalities, therefore the motor becomes
uncontrolled; this could cause the stoppage or idle motor ( for a
period determined by the type of system used).
In some cases the drive could restart automatically when the
reason for blockage is corrected.
In this case, some systems could be damaged or destroyed
endangering the welfare of personnel.
In this case the user must remove the drives' and systmes' power
supply so that the motor cannot automatically restart or prevent
such an event in the controller's program.
The Microspeed Plus terminals must always be grounded as per
the instructions in this manual.

Capitolo 1
1.1 Introduction
General Description
The Microspeed Plus Servo Amplifier is a compact full DC four
quadrant drive. The (MOSFET)output power stage is controlled
by a 22 Khz PWM (Pulse With Modulation)signal that allows it t
drive small to medium sized brushless servo motors (up to 6Nm)
where high dynamic performance and precise speed is required.
The Microspeed only requires a single power supply to operate
and develops all needed voltages on board to make power supply
design easy and convenient.The input voltage is from 20 to 270
Vdc max "See Tecnical Data". (Chapter 3 describes how to design
a proper supply.)
Closing the velocity feedback loop to motor may be done in
several different ways to accommodate most applications. Three
types of velocity feedback are available with these drives. Refer
to Chapter 5 for the setup procedures that will effect your
application.
Feedback Types:
-Tachogenerator
-Armature.
-Encoder (Option)
-Pwm+Direction (Option)
Two inputs are present for the disabling of clockwise and counter-
clockwise motor rotation (+LM SW,-LM SW).
The possibility to completely adjust the Dynamic Constant exists
by inserting new values "as opposed to the standard mounted
values".
The insertion of various prearranged operational drive values
are easily realized by opening and closing solder points. The
intervention of drive protections are all visible with LEDs on the
front of the drive.
The nominal current, as well as peak current is adjusted through
resistance on the base.
The operating temperature is from 0 to +40 °C (32° to 104°F).
In accordance with the current size and model, supplemental
ventilation can be requested.
