– Ambient temperature between –20 °C and +40 °C
– No oil, acid, gas, vapors, radiation, etc.
– Installation altitude max. 1000 m above sea level
– Special designs: Drive configured in accordance with the ambient conditions
4.3Preliminary work
Motor shaft ends must be thoroughly cleaned of anti-corrosion agents, contamination or
similar (use a commercially available solvent). Make sure that the solvent does not come
into contact with the bearing or sealing rings as it may damage the material.
NOTICE
The bearing and the sealing rings can be damaged if exposed to solvents.
Potential damage to property.
•Protect the bearing and sealing rings from exposure to solvents.
4.3.1Installation after extended storage
•Note that the service life of the lubricant in the ball bearings is reduced by 10% per
year after the first year of storage.
•Check whether the motor has absorbed moisture as a result of being stored for a long
time. Measure the insulation resistance for this purpose (measuring voltage
DC 500 V).
The insulation resistance (see following figure) varies greatly depending on the temperature. The motor must be dried if the insulation resistance is not adequate.
The following figure shows the insulation resistance depending on the temperature.
[MΩ]
100
4.3.2Drying the motor
TIP
Insulation resistance too low:
→ Servomotor has absorbed moisture
Measure:
•Use hot air to heat up the motor.
•Open the motor compartment enough for moisture to escape from the inside.
Next check whether:
•The wiring space is dry and clean.
•The connections and fastening parts are free from corrosion.
•The joint seal is functioning.
•The cable glands are tight, otherwise clean or replace them.
Vertical designs with VR forced-cooling fan can get damaged by foreign objects or
moisture.
Potential damage to property.
•Protect vertical designs with VR forced-cooling fan with corresponding covers.

If a forced cooling fan is used, ensure there is sufficient clearance around the unit to
allow for adequate cooling. Make sure that the unit does not suck in hot outgoing air from
other units.
Components with a keyway to be mounted belatedly on the shaft must be balanced
using a half key. Motor shafts may be balanced with a half key (vibration level "N" to
EN/IEC 600 34). You must not operate the motor without a key.
•It is essential to comply with the safety notes in section 2 during installation.
•Use switch contacts in utilization category AC-3 to EN 60947-4-1 for connecting
the motor and the brake.
•When motors are powered from inverters, you must adhere to the wiring
instructions issued by the inverter manufacturer.
•Observe the operating instructions for the servo inverter.
5.1Assembling the connector
NOTICE
If the connector is tightened when it is installed in the wrong position, the insulator could
slip, causing irreparable damage.
Potential damage to property.
Note the following when plugging in the power and signal connectors:
•Check that the connector is installed in the correct position.
•Check that the detent on the connector is positioned correctly.
•Make sure that the connector lock can be turned without having to apply too much
force.

5.3.2Prefabricated cables
Pre-fabricated cables are available from SEW-EURODRIVE to connect the SM../SB..
plug connector system. The core designation and contact assignment are listed in the
following tables.
Observe the following when you assemble the cables yourself:
•Section 10 describes the assembly of the SM1./SB1., SM5./SM6., SB5./SB6 power
connectors and the signal connector.
•The socket contacts for the motor connection are designed as crimp contacts. Only
use suitable tools for crimping.
•Strip the insulation of the leads according to section 10.
•Use suitable removal tools to remove incorrectly installed socket contacts.
•Install the insulator in the signal connectors on the motor end at "zero" degree (center
position). Observe this coding on the cable end.
•Cable relief according to EN 61984 and EN 60529 is influenced by the tightening
torque of the screw. The tightening torque must be matched to the cable.
These data are merely recommended values and are no substitute for the detailed
project planning of the cables depending on the concrete application considering the
applicable regulations.
Observe the voltage drop that occurs along the cable in particular with the DC 24 V
brake coil when dimensioning the cross sections for the brake cable. The accelerator
current is decisive for the calculation.

Check/correct setting of frequency inverter according to
The amount of wear depends on many factors and may be high. The machine designer
must calculate the required inspection intervals individually in accordance with the
project planning documents (e.g. Drive Engineering – Practical Implementation: Drive
Project Planning, Servo Gearmotors catalog).
TIP
Observe the manufacturer's notes in the respective maintenance schedule.
Excessive dirt, dust or shavings can have a negative impact on the function of servomotors; in extreme cases these factors can cause the servomotor to break down.
Therefore, you must clean the servomotors at regular intervals (after one year at the latest) to ensure a sufficiently large area for heat emission.
Insufficient heat emission can have unwanted consequences. The bearing service life
is reduced through operation at impermissibly high temperatures (bearing grease degrades).
8.2.2Connection cables
DANGER
The servomotor has live parts during and after operation.
Severe or fatal injuries from electric shock.
•De-energize all power, brake and signal cables before unplugging the power or
signal plug connector.
•Safeguard against accidental startup.
•Do not perform temporary repairs on the connection cables. When the cable jacket
is defective, no matter how small the fault, shut down the system immediately and
replace the cable.
Check the connection cable for damage at regular intervals and replace if necessary.
8.3Inspection work for the B brake (DFS)
The DFS56 brake does basically not require any maintenance work. The brake can not
be retrofitted.
NOTICE
The motor must be disassembled when replacing the brake which cannot be adjusted.
Possible damages to the B brake.
•Only SEW-EURODRIVE may perform maintenance on the B brake because the
encoder or resolver has to be reset each time the system is disassembled.
The servomotor has live parts during and after operation.
Severe or fatal injuries from electric shock.
•De-energize all power, brake and signal cables before unplugging the power or
signal plug connector.
•Safeguard against accidental startup.
CAUTION
The surface temperature of the servomotor can exceed 100 °C during operation.
Danger of burns
•Never touch the servomotor during operation or in the cool down phase once the it
has been switched off.
•Let the servomotor cool down before you start your work.
•Wear protective gloves.
Inspection/Maintenance

The working air gap cannot be readjusted and can only be measured via the stroke of
the pressure plate when the brake is released.
•Isolate the motor and brake from the supply, safeguarding them against unintentional
power-up.
•For motors with a forced-cooling fan, remove the metal cover from the motor.
•Connect the brake to the power supply.
•Via the stroke of the pressure plate measure the working air gap that appears during
the electrical application/release process, using the two pressure pins ΔH (see following figure). A range of 0.15 ... 0.8 mm is permitted.
ΔH
•If the working air gap > 0.8 mm, replace the entire brake. Only SEW-EURODRIVE
may replace the brake.
