Presentation
The modular range of Lexium 32i integrated servo drives features three control units
for controlling Lexium BMI servo motors. These servo motors integrate the power
stage that provides a direct power supply from either a single-phase or three-phase
AC supply.
The Lexium 32i thus offers optimum functionality that can adapt to the specic
performance, power, and simplicity of use requirements of motion control
applications.
It covers power ratings between 0.4 and 2.1 kW.
The Lexium 32i range of integrated servo drives is designed to simplify the life cycle
of machines. SoMove setup software simplies initial startup. The modular design
facilitates installation by reducing assembly time to as little as three minutes and
makes maintenance easier. Maintenance is also quicker and cheaper thanks to the
new duplication and backup tools, like the memory card.
Performance is improved through optimized motor control achieved through reduced
vibration with automatic parameter calculation, a speed observer, and an additional
band-stop lter. This optimization helps to increase machine productivity.
The compact size of the Lexium 32i provides maximum power in minimum space,
which helps to reduce the size of the enclosure required by up to 60% and the direct
and indirect costs by up to 30%.
Three control units - CANopen/CANmotion, EtherCAT and Ethernet (PROFINET) allow adaptation to numerous industrial control system architectures.
The integrated Safe Torque Off function reduces system design times and makes it
easier to comply with safety standards.
Applications for industrial machines
The Lexium 32i integrated servo drive incorporates functions that are suitable for the
most common applications, including:
b printing - cutting, position-controlled machinery, etc.
b packing and wrapping - cutting to length, rotary knife, bottling, capsuling,
labeling, etc.
b textiles - winding, spinning, weaving, embroidery, etc.
b material handling - conveying, palletizing, warehousing, pick-and-place, etc.
b transfer machines - gantries, hoists, etc.
b clamping
b ying shear operations - cutting, printing, marking, etc.
b materials processing, etc.

The offer
The Lexium 32i range of integrated servo drives covers motor power ratings
between 0.4 kW and 2.1 kW with three types of power supply:
b 110…120 V single-phase, from 0.4 kW to 0.75 kW (BMIpppTppp)
b 200…240 V single-phase, from 0.7 kW to 1.3 kW (BMIpppTppp)
b 208…480 V three-phase, from 0.4 kW to 2.1 kW (BMIpppPppp)
Compliance with international standards and certications
The entire range conforms to international standards IEC/EN 61800-5-1 and
IEC/EN 61800-3, is UL and CSA certied, and has been developed to meet the
requirements of directives regarding protection of the environment (RoHS) as well as
those of European directives to obtain the e mark.
Compliance with electromagnetic compatibility (EMC) requirements
The integration of category C2 EMC lters in Lexium 32i servo drives and
compliance with EMC simplify installation and make it very inexpensive to bring the
device into conformity to obtain the e mark.
These lters comply with standard IEC/EN 61800-3, environment 1, category C2.
Accessories and options
External accessories and options, such as braking resistors and planetary
gearboxes, enhance this offer.

SoMove setup software 1 SoMove setup software is used in just the same way as it is on other Schneider
Electric drives and starters, to congure and optimize control loops in automatic or
manual mode using the Oscilloscope function and for maintenance of the Lexium 32i
integrated servo drive.
See page 14 or consult our catalog n° DIA2ED2140801EN on our web site www.
schneider-electric.com
Multi-Loader tool 2 The Multi-Loader tool is used to copy congurations from a PC or Lexium 32i servo
drive and load them onto another Lexium 32i.
See page 14.
Memory card 3 This stores the control unit parameters. When replacing a Lexium 32i, this function
helps to ensure immediate startup by removing the need to program the drive. This
optimizes maintenance time and reduces costs.
See page 14.
Auto-tuning Adapted to each user, the three auto-tuning levels - automatic, semi-automatic, and
expert - allow you to achieve a high level of machine performance, whatever the
application.

High performance
The following Lexium 32i offer features help to increase machine performance:
b Overload capacity: The high peak current (up to 4 times the direct current)
increases the range of movement.
b Power density: The compact size of the drives offers maximum efciency in a
small space.
b High bandwidth: Better speed stability and faster acceleration improve the quality
of control.
b Motor control: Less vibration, a speed observer, and an additional band-stop lter
enhance the quality of control.
Design suitable for different control system structures
The versatility of the Lexium 32i range offers excellent exibility for integration into
different control system structures.
Depending on the model, the Lexium 32i has logic inputs and outputs, which can be
congured according to application requirements.
It also has three control unit types for managing the communication via:
b CANopen/CANmotion machine bus
b EtherCAT machine bus
b Ethernet (PROFINET) network
Dedicated safety functions
The Lexium 32i range is an integral part of a control system's safety system,
featuring as it does an integrated Safe Torque Off (STO) function, which helps to
prevent unintended servo motor operation.
This function complies with standard IEC/EN 61508 level SIL3 governing electrical
installations and the power drive systems standard IEC/EN 61800-1.
It simplies the setup of installations requiring complex safety equipment and
improves performance during maintenance operations by reducing the time required
for servicing. The bus connection module with STO option is required to access this
function (see page 10).

Lexium BMI servo motors - dynamic and powerful
Lexium BMI servo motors are synchronous three-phase motors. They feature a
SinCos Hiperface® for automatic transmission of data from the servo motor to the
control units and are available with or without a holding brake.
Lexium BMI servo motors provide high power density values to optimize machine
compactness. Available with two ange sizes and two different lengths for each
ange size, they are suitable for most applications, covering a continuous torque
range from 1.7 to 7.2 Nm for speeds up to 4700 rpm. They cover the power range
0.4 to 2.1 kW.
BMI servo motors have a medium inertia motor, which means they are particularly
suitable for medium and high-load applications. They help to simplify installation and
adjustment through a more robust adjustment of the movement.
Lexium BMI servo motors are UL Recognized and conform to standard UL1004
as well as to European directives (e marking).
They are available with the following variants:
b 2 ange sizes: 70 and 100 mm/2.76 and 3.94 in.
b 2 degrees of protection for the shaft end: IP 54 or IP 65 in accordance with
standard IEC/EN 60529 (the degree of protection of the casing is IP 65)
b with or without holding brake
b integrated single-turn or multi-turn SinCos Hiperface® encoder (standard or high
resolution)
b smooth or keyed shaft end
