gral part of the product and contain important information for operation and service.
They are intended for staff responsible for the assembly, installation, startup and main-
tenance of the product.
The operating instructions and the addendum to the operating instructions must be leg-
ible and accessible at all times. Make sure that staff responsible for the plant and its op-
eration, as well as persons who work independently on the unit, have read the operating
instructions and the addendum to the operating instructions carefully and understood
them. If you are unclear about any of the information in this documentation, or if you re-
quire further information, contact SEW-EURODRIVE.

Designated use
Safety Notes
2.4 Designated use
The designated use refers to the procedure specified in the operating instructions and
the addendum to the operating instructions.
CMP and CMPZ synchronous servomotors are drive motors designed for use in indus-
trial and commercial systems. Motor utilization other than that specified and areas of ap-
plication other than industrial and commercial systems can only be used after consulta-
tion with SEW-EURODRIVE.
The CMP and CMPZ synchronous servomotors meet the requirements of the low volt-
age directive 2006/95/EC. Do not take the unit into operation until you have established
that the end product complies with the EC Machinery Directive 2006/42/EC.
You must observe the technical data and information on the connection requirements
as provided on the nameplate and in the documentation.
2.5 Functional safety (FS)
Observe the notes and measures described below.
2.5.1 Labeling
If functional safety is integrated in the motor, this is indicated with a FS symbol on the
nameplate.
2.5.2 Encoder
The described, safety-rated encoders can only be used with this motor. It is not possible
to adapt them to other motors.
The safety-related use of encoder systems is necessary for implementing safety-related
functions regarding speed, direction of rotation and standstill from the encoder that is
coupled directly with the motor shaft. A higher-level, safe evaluation unit is required in
addition, as the encoder with its encoder-internal diagnostic function is not able to trigger
responses such as initiating a safe status on its own initiative.
Increased demands are placed on the electrical and mechanical coupling, e.g. the
shielded connection lead stranded in pairs, and the strict observation of the assembly
instructions.
AK0H The RS485 interface (Hiperface®) cannot be used in connection with safety technology
for transferring absolute position data and other data (nameplate, diagnostics) due to
the relatively long transmission time. This information can be used for general diagnostic
purposes.

2Transportation/storage
Safety Notes
2.6 Transportation/storage
Follow the instructions on transportation, storage and proper handling.
Inspect the shipment for any damage that may have occurred in transit as soon
as you receive the delivery. Inform the shipping company immediately. If you no-
tice any transport damage, do not startup the motor, consult the SEW-
EURODRIVE Service.
Remove securing devices used for transportation prior to startup.
Tighten installed transportation eyebolts. They are designed to only carry the weight of
the motor/gearmotor; do not attach any additional loads.
The installed lifting eyebolts comply with DIN 580. The loads and regulations
specified in this standard must always be observed. If the gearmotor has 2 sus-
pension eye lugs or lifting eyebolts, then you should also use both suspension
eye lugs for attaching transport ropes. In this case, the tension force vector of the
slings must not exceed a 45° angle according to DIN 580.
Store the servomotor in a dry, dust-free environment if it is not to be installed straight
away. The servomotor can be stored for one year without requiring any special mea-
sures before startup.
2.7 Mounting/installation
Observe the instructions in chapter "Mechanical Installation" and chapter "Electrical In-
stallation" of the detailed operating instructions.
The units must be installed and cooled according to the regulations and specifications
in the corresponding documentation.
Protect the synchronous servomotors from excessive strain. Ensure that components
are not deformed, particularly during transportation and handling.
INFORMATION
• Screw in the lifting eyes all the way.
• Make sure that the lifting eyes carry only a reduced load, as the angle of the load
exceeds 45°.
• Due to the angle of the load, the lifting eyes are oversized. Note that the lifting eyes
are not designed to hold the entire load of the gear unit.
