Rexroth IndraDyn A Introduction to the Product 1-1
1 Introduction to the Product
The IndraDyn A series consists of housed, asynchronous motors from
Bosch Rexroth. The two versions of IndraDyn A differ by their method of
cooling.
•The MAD version is air-cooled by a firmly-attached fan unit, which
forces the ambient air across the surface of the motor.
MAD.jpg
Fig. 1-1: Illustration example MAD130
•The MAF version is internally cooled by liquid.
MAF.jpg
Fig. 1-2: Illustration example MAF130
IndraDyn A motors can be used either as main-spindle motors or as servo
motors for all rotary drive applications.
The optimized design has international protection class IP65 for both
motor and fan which allows for operation in adverse conditions. The easy-
to-service construction reduces maintenance frequency and even allows
maintenance during operation.
Combined with digital control devices from the IndraDrive series, this
results in intelligent drive solutions with a high power density and open
functions.

1-4 Introduction to the Product Rexroth IndraDyn A

Rexroth IndraDyn A Important directions for use 2-1
2 Important directions for use
2.1 Appropriate use
Introduction
Bosch Rexroth products represent state-of-the-art developments and
manufacturing. They are 100% tested prior to delivery to ensure operating
safety and reliability.
The products may only be used in the manner that is defined as
appropriate. If they are used in an inappropriate manner, then situations
can develop that may lead to property damage or injury to personnel.
Note: Bosch Rexroth, as manufacturer, is not liable for any damages
resulting from inappropriate use. In such cases, the guarantee
and the right to payment of damages resulting from
inappropriate use are forfeited. The user alone carries all
responsibility of the risks.
Before using Bosch Rexroth products, make sure that all the pre-
requisites for appropriate use of the products are satisfied:
•Personnel that in any way, shape or form uses our products must first
read and understand the relevant safety instructions and be familiar
with appropriate use.
•If the product takes the form of hardware, then they must remain in
their original state. In other words, no structural changes are
permitted. It is not permitted to decompile software products or alter
source codes.
•Do not mount damaged or faulty products or use them in operation.
•Make sure that the products have been installed in the manner
described in the relevant documentation.

2-2 Important directions for use Rexroth IndraDyn A
Areas of use and application
Asynchronous motors of the IndraDyn A line made by Bosch Rexroth are
designed to be used as rotary main-spindle and servo-drive motors.
Typical applications are in:
•machine tools,
•printing and paper processing machines,
•packaging and foodstuff machines and
•metal-forming machine tools.
Several types of motors with differing drive power and different interfaces
are available for application-specific uses.
Control and monitoring of the motors may require additional sensors and
actors.
Note: The motors may only be used with the accessories and parts
specified in this document. If a component has not been
specifically named, then it may not be either mounted or
connected. The same applies to cables and lines.
Operation is only permitted in the specified configurations and
combinations of components using the software and firmware
as specified in the relevant function descriptions.
Every drive controller has to be programmed before starting it up, making
it possible for the motor to execute the specific functions of an application.
The motors may only be operated under the assembly, installation and
ambient conditions as described here (temperature, IP-Class, humidity,
EMC requirements, etc.) and in the position specified.
2.2 Inappropriate use
Inappropriate use is defined as using the motors outside of the above-
referenced areas of application or under operating conditions other than
described in the document and the technical data specified.
IndraDyn A motors may not be used if
•they are subject to operating conditions that do not meet the above
specified ambient conditions. This includes, for example, operation
under water, in the case of extreme temperature fluctuations or
extremely high maximum temperatures or if
•Bosch Rexroth has not specifically released them for that intended
purpose. Please note the specifications outlined in the general Safety
Guidelines!

Touching live parts with voltages of 50 Volts and more with bare hands or
conductive tools or touching ungrounded housings can be dangerous and
cause electric shock. In order to operate electrical equipment, certain
parts must unavoidably have dangerous voltages applied to them.
DANGER
High electrical voltage! Danger to life, severe
bodily harm by electric shock!
⇒
Only those trained and qualified to work with or on
electrical equipment are permitted to operate, maintain
or repair this equipment.
⇒
Follow general construction and safety regulations when
working on high voltage installations.
⇒
Before switching on power the ground wire must be
permanently connected to all electrical units according
to the connection diagram.
⇒
Do not operate electrical equipment at any time, even
for brief measurements or tests, if the ground wire is not
permanently connected to the points of the components
provided for this purpose.
⇒
Before working with electrical parts with voltage higher
than 50 V, the equipment must be disconnected from
the mains voltage or power supply. Make sure the
equipment cannot be switched on again unintended.
⇒
The following should be observed with electrical drive
and filter components:
⇒
Wait thirty (30) minutes after switching off power to
allow capacitors to discharge before beginning to work.
Measure the voltage on the capacitors before beginning
to work to make sure that the equipment is safe to
touch.
⇒
Never touch the electrical connection points of a
component while power is turned on.
⇒
Install the covers and guards provided with the
equipment properly before switching the equipment on.
Prevent contact with live parts at any time.
⇒
A residual-current-operated protective device (RCD)
must not be used on electric drives! Indirect contact
must be prevented by other means, for example, by an
overcurrent protective device.
⇒
Electrical components with exposed live parts and
uncovered high voltage terminals must be installed in a
protective housing, for example, in a control cabinet.

3-6 Safety Instructions for Electric Drives and Controls Rexroth IndraDyn A
To be observed with electrical drive and filter components:
DANGER
High electrical voltage on the housing!
High leakage current! Danger to life, danger of
injury by electric shock!
⇒
Connect the electrical equipment, the housings of all
electrical units and motors permanently with the safety
conductor at the ground points before power is
switched on. Look at the connection diagram. This is
even necessary for brief tests.
⇒
Connect the safety conductor of the electrical
equipment always permanently and firmly to the
supply mains. Leakage current exceeds 3.5 mA in
normal operation.
⇒
Use a copper conductor with at least 10 mm² cross
section over its entire course for this safety conductor
connection!
⇒
Prior to startups, even for brief tests, always connect
the protective conductor or connect with ground wire.
Otherwise, high voltages can occur on the housing
that lead to electric shock.
3.6 Protection Against Electric Shock by Protective Low
Voltage (PELV)
All connections and terminals with voltages between 0 and 50 Volts on
Rexroth products are protective low voltages designed in accordance with
international standards on electrical safety.
WARNING
High electrical voltage due to wrong
connections! Danger to life, bodily harm by
electric shock!
⇒
Only connect equipment, electrical components and
cables of the protective low voltage type (PELV =
Protective Extra Low Voltage) to all terminals and
clamps with voltages of 0 to 50 Volts.
⇒
Only electrical circuits may be connected which are
safely isolated against high voltage circuits. Safe
isolation is achieved, for example, with an isolating
transformer, an opto-electronic coupler or when
battery-operated.
