2 Risks and Precautions
A T T E N T I O N
Following are listed the most important warnings to be fully comprehended and applied by
the user who, in case of non-complete comprehension or impossibility to apply them correctly,
must not use the product at all.
The DS10xx drivers are components. It is user’s responsibility as the
installer to be sure the product complies with the rules and regulations
in force. The user must also be trained in the installation of the
electronic equipment to fully comprehend the features, the calibration
parameters and indications contents of this guide.
The user must provide for the application of all the local safety laws and
regulations in force in the Country and/or application in which the
product is used.
The user must provide that the product is inaccessible while powered
on. The user must also consider that, because of the capacitors inside
the driver, it is necessary to wait at least for 30 seconds after the power
off before acceding to the driver. According to the external capacitors
eventually mounted on the power supply circuit, it is possible the user
shall have to wait more time.
While working the product produces heat which can raise the
temperature of some parts (as heat sink, for example) up to values that
can cause burns. Such a condition remains for a long time even after
the product has been powered off. The user must provide for the
appropriate protections and signals, must train the operator, the staff of
the technical support and risk maintenance, and then must state it in the
service manual of the finished product.

Risks and Precautions DS10xx
8
The high performance driver is able to produce rapid accelerations with
high motor torque. Never touch any mechanical part while the driver is
powered on. The user must prearrange the application in order this
condition is always granted.
The power supply of the product must be isolated from the electrical
net. The user must always place a protective fuse in series to the power
supply circuit.
The control signals are usually isolated from the power supply while the
product is in operation; anyway, while designing the application, the
eventuality that in case of breakdown these lines could reach the same
potential as the power supply must be considered to meet safety
requirements.
The product could be permanently damaged by corrosive substances
(such as gas, salts, etc), liquids or conductive dusts. Even a long and
constant exposure to strong vibrations could cause the damage.
On some damage conditions the driver could emit sparks and fire. The
cabinet and the nearby components must be chosen to tolerate this
eventuality and to avoid propagation of flames to the application.
The products cannot be used in life support applications or where the
failure of the products could cause death or injury to people, animals or
things, or economic losses. The user not able to assure this condition
must not use the products herein described.

DS10xx Risks and Precautions
9
Do not dismantle the product, do not try and repair it and do not modify
it without being expressly authorized by LAM Technologies.
If the product is used in any manner that does not comply with the
instructions given in this manual, then the product could be permanently
damaged. For example, the product could be permanently damaged if
power supplied with voltage superior to the allowed one, if supply
polarity is inverted, if the motor is connected or disconnected while the
driver is operating, and so on.

DS10xx Introduction

3 Introduction
3.1 Product Description
The DS10xx High Performance Microstepping Drivers are suitable for
driving bipolar two phase stepping motors.
The current regulation is particularly cared and optimized and provides
accurate position and smoothness movement of the motor. The use of last
generation power components together with the development of an
innovative control system its has been possible to reach high level of
efficiency, to be compact sized and to reduce driver heating.
The high technology in the product has allowed to overcome the previous
full step or fractioned limited step solutions, offering at the same price a
product able to drive in microstepping mode with an high step frequency.
The DS10xx drivers series is equipped with a special port called DUP,
designed for the setting and diagnostics of the driver.
Through this special device it is possible to intervene on many more
parameters than the minimum ones allowed by the dip switches, and to
adapt in the best way the driver to the application. The bundled driver
software guides the user in the product configuration simply and quickly
and assists the user in the diagnostic giving in real time indications on the
status of driver, inputs, outputs, etc.
The use of last generation components and technologies, together with the
computerized test made on each single unit, gives to the product itself high
reliability and economic competitiveness.
3.1.1 Available models
The DS10xx family drivers are available in various models diversified
according to the power supply voltage and the phase current delivered by
the motor. All the models share the same functional features:

4 Installation
4.1 Inspection Verify the driver is not damaged, the package is intact and all accessories
of the ordered product are included. Furthermore, control the driver code
corresponds to the ordered one, eventual special and customized version
included. In case of problems please address to the product’s vendor.
4.2 Mechanical Installation
The driver is designed to be mounted vertically on a 35mm DIN rail.
To block the driver on the DIN rail, insert first the bracket on the top, on
the back of the driver, over the top of the DIN rail, keeping the driver
slightly inclined as shown in the figure, then push the driver downward to
engage the lower section of the rail. To verify the correct engagement of
the driver try and pull it slightly upward to control it is still in position.

To remove the driver from the DIN rail insert a small flat bladed
screwdriver into the red colored hook on the bottom, on the back of the
driver. Push the hook downward and pull the driver upward slightly
rotating it, releasing it from the DIN rail as shown in the figure.

The heat generated by the driver while operating must be dissipated toward
the surrounding air. To assist cooling, the driver must be installed vertically
in an area with a sufficient air gap of about 50mm above and below the
driver itself, with no obstructions (wiring cables are anyway allowed). No
space needs to be left on the sides and more drivers can be packaged side
by side taking a very compact space.
According to the driver calibration and to the running cycle, the space can
be also substantially reduced without compromising the correct working of
the driver.

4.3 Air Cooling Its exceptional efficiency allows the product to be used even if absence of
forced ventilation.
Whereas the driver is used with high calibration current or at high power
supply voltage, whereas the working cycle is very heavy or the ambient
temperature is high, it is possible to recur to forced ventilation to maintain
the driver temperature within the functioning range values.
The fan can be positioned over or under the driver. A lateral position is not
recommended. Thanks to the compact size of the driver, an only and
economic fan of 120mm x 120mm can supply air circulation sufficient for
6 drivers simultaneously (models of 18mm wide).

In case of a reduced size fan, it must be set in a rear position and at about
30mm high from the driver. A nearer or more distant position could reduce
its effectiveness.
It is important to avoid the driver is covered with powder, dust or other.
The buildup of such substances inside the driver could cause the
malfunctioning or the breaking of the driver. Filters and necessary solutions
must be got ready to avoid them to occur.
