The German version is the original of this document.
Multi-axis system ServoOne CM
Consisting of the ServoOne CM-P supply unit, the DC-powered ServoOne CM axis
controllers and a matching controller MotionOne CM, the compact multi-axis system
SystemOne CM offers a high degree of solutions expertise and exibility in the range
from 2 A to 210 A rated current.
With the aid of the ServoOne SO CM-E expansion module, the ServoOne CM axis
controllers BG1+2 can be combined with the ServoOne CM axis controllers BG3+4
without problems.
The addition of the ServoOne CM-C capacitance module to the ServoOne CM-P supply
unit BG3+4 makes possible usage in even more dynamic applications.
The external ServoOne CM-S switched-mode power supply is also available for the 24 V
control supply.
Reduction of the wiring and shortening of the installation times are just as easy to
achieve as resource-saving, cost-conscious operation.
Usage of the expansion module:
It is used to protect, monitor and adapt the smaller cable cross-section (DC link = lower
current carrying capacity) on the axis controllers SO CM BG1+2 to the larger cable
cross-section (DC link = higher current carrying capacity) on the axis controllers SO CM
BG3+4.

3.1 Notes for installation
During the installation work it is imperative you avoid ...
yDrill chippings, screws or other foreign bodies falling into the device
yMoisture entering the device
Switch cabinet
yThe device is designed only for installation in a stationary switch cabinet. The
switch cabinet must as a minimum provide IP4X protection. According to
ENISO13849-2 the switch cabinet must have IP54 protection or higher when
using the safety functions (STO and SBC in the axis controller).
Environment
yThe ServoOne CM-E module must not be installed in areas where it would be
permanently exposed to vibration. You will nd more information in the appen-
dix.
Soiling
yMaximum pollution degree 2 in accordance with EN60664-1. Further informa-
tion on ambient conditions can be found in the appendix.
Effective EMC installation
yTo obtain the best result for effective EMC installation you should use a conduc-
tive, well-earthed, chromated or galvanised backing plate.
If backing plates are varnished, remove the coating from the contact area! The devices
themselves have a chromated zinc frame.
NOTE:
On installing the CM-E module in the axis group, it is imperative the operation
manuals for the other devices (supply unit, controller, etc.) are also followed.
3.1.1 Order and arrangement
The following basic guidelines apply to the arrangement and installation of the CM-E
module:
Butt mounting and alignment
yThe devices can be mounted directly beside each other without any spacing.
They are fastened to the backing plate using two screw joints.
yAll devices in the axis group - supply unit (SO CM-P), axis controller (SO CM)
and the controller (MO CM) - are connected together using the 24 V busbars.
Given the same cooling concept, these connections can be made without addi-
tional compensation measures in relation to the device depth.
yDC link busbars are available for the power supply. The ServoOne CM axis
controllers BG3+4 are to be connected on the left side of the ServoOne CM-E
expansion module, the ServoOne CM axis controllers BG1+2 are to be con-
nected on the right side.
yThe devices must be mounted in the stipulated order one against the other see
Bild 3.1. A different order is not allowed, as otherwise there will be problems
with the busbars and the thermal interaction between the devices.
CAUTION! Damage to the device due to incorrect installation conditions!
The device may suffer irreparable damage if the conditions are not met.
• The direct connection of the DC link connections between SO CM BG3/4 and SO CM BG1/2
without an SO CM-E module is not allowed. Devices may be irreparably damaged if this
instruction is not followed.

4 Electrical installation
4.1 Before you start
During the installation work it is imperative you avoid ...
yScrews, cable residue or other foreign bodies falling into the device
yMoisture entering the device
DANGER! Risk of injury due to electrical power!
Carelessness will result in serious injuries or death.
Never make or disconnect electrical connections while they are electrically live! Always
disconnect the power before working on the supply unit. Even 3min. after switching off the mains
supply, dangerously high voltages of ≥50V may still be present (capacitor charge). Therefore
always check electrical power is not present!
Only once the DC link voltage has dropped to a residual voltage of less than 50V (to be
measured at the DC link busbars) is it allowed to work on the device.
Pay attention to warning sign on the device (see front of device).
NOTE:
On installing the expansion module in a ServoOne CM multi-axis system, it is
imperative the operation manuals for the other devices (axis controllers, supply
unit) are also followed.
4.2 Effective EMC installation
Compliance with the EMC product standard
Commissioning i.e. start-up of intended operation is only permitted on strict compliance
with the EMC Directive (2014/30/EU). The installer/operator of a machine and/or system
must provide proof of compliance with the protection targets stipulated in the standard.
The essential EMC measures are already implemented in the design of the devices in
the form of optimised housing shielding, printed circuit board layout, lter measures and
selection of suitable connectors with shield plate. In addition to the internal measures,
the following installation measures are to be noted:
17
Electrical installation
Operation Manual Expansion Module SO CM-E
1800.202B.0-01 Date: 02/2019
Routing of cables
yIf possible, signal cables should only enter from one side into the switch
cabinet.
yIt is recommended to twist lines of the same electrical circuit.
yAvoid unnecessary cable lengths and "loops of spare cable".
Shielding measures
yA shielded connection cable is not necessary for the connection of the
expansion module.
Cable type
yIf stipulated, please use shielded cables with double copper braiding with 60%
to 70% coverage. To connect LTi servomotors we recommend the usage of
pre-assembled motor and encoder cables from LTI Motion, as all EMC tests
have been undertaken successfully with these cables.
NOTE:
If connection cables from other suppliers are used, these cables must as a
minimum be equivalent. However, an assurance of stable, reliable operation
with such cables cannot be given by LTI Motion.
Earthing measures
yThe devices are to be fastened to a conductive, earthed backing plate. Earthing
measures to EN61800-5-1 are described in Chapter 4.4.
External components
yPlace larger loads near the supply.
yContactors, relays, solenoid valves (switched inductances) must be wired with
suppressors. The wiring must be directly connected to the respective coil.
yAny switched inductance should be at least 0.2m away from the process-
controlled assemblies.
If you require further detailed information on installation, you should consult the
LTIMotion Helpline, see Chapter 1.11.

4.4 Protective earth conductor connection
Step Action Comment
1.
Connect the PE connections on the expansion module, the supply
unit, the axis controllers and the controller etc. to the PE rail (main
earth) in a star topology, see Figure 4.2.
Each device in the axis group
must be earthed!
2.
Connect the protective earth conductor connections on all other
components, such as mains lter*), mains choke*) etc. in a star
topology to the PE rail (main earth) in the switch cabinet.
*) Components are only
required for the ServoOne
CM-P supply unit.
4.4.1 PE connection in accordance with DIN EN 61800-5-1
The leakage current is > 3.5 mA. This situation results in the following minimum
requirements for the protective earth conductor cross-section as a function of the phase
conductor cross-section, as per EN61800-5-1.
Cross-section of the phase conductors Minimum cross-section
of the corresponding protective earth conductor
Q ≤ 16 mm2 Q however at least 10 mm2 (Cu)
16 < Q ≤ 35 mm2 16 mm2 (Cu)
Q > 35 mm2 Q/2
Table 4.3 Protective earth conductor cross-section
CAUTION! Risk of injury due to incorrect wiring!
Carelessness may result in injuries.
The protective earth conductor connection is a safety feature. Therefore, make sure that all
connections have good contact and are sufciently secure that they cannot come loose.
NOTE:
Always comply with local and national regulations and conditions.

Figure 4.3 Electrical isolation concept with key
4.5 Electrical isolation concept
The control terminals are designed as protective extra low voltage
(PELV) circuits and must only be operated with such PELV voltages,
as per the relevant specication. This aspect provides reliable
protection against electric shock.
The connections DC Link +/-, Motor1 U/V/W, Motor2 U/V/W are at
mains potential (low voltage).
The overview opposite shows the potential references for the
individual connections in detail. This concept also delivers better
operational safety and reliability of the axis controllers.
