Notes on safe operation
The robot coupling may pose a danger to persons (risk of injury)
and property if, for example:
• it is not used as intended;
• it is not installed or maintained properly;
• The safety and installation instructions, local applicable safety
and accident prevention regulations or the Machine Directive
are not observed.
NOTES
During automated loading or unloading, particularly with high
loading weights, always work with the handling system at reduced
speed. The handling system must be positioned and fastened
precisely to guarantee that the connection is not offset.
Check the approach position of the pallet handling at regular
intervals. The position of the handling system can change slightly,
particularly with high load weights or when the clamping pallet is
bearing the loading weight significantly towards the front. In the
event of eccentricity on the coupling interfaces, the relevant
traveling axes of the handling system must be adjusted. The robot
coupling must lie flush with the pallet coupling with no tilt angle
and eccentricity when joining.
A rigid handling system must be used with high loading weights.
For the automated coupling process, it is advisable to use the air
purge to clean the coupling interface.
The pallet handling should be moved out of the machining area
once pallet loading is complete. On leaving the machining area,
the clamping system must be positioned to prevent dirt from
entering the interface.
Maintenance specifications
Follow the maintenance and care instructions. These instructions
are based on a normal working environment. If the robot coupling
is to be operated in an environment with abrasive dusts or
corrosive or caustic fumes or fluids, prior approval must be
obtained from SCHUNK.

Safety during assembly and servicing
During assembly, connection, adjustment, commissioning and
testing, make sure that no accidental operation of the robot
coupling by the fitter or other persons is possible.
Avoid any unsafe manner of working.
Holding force and screw strength
The holding force of the robot coupling is essentially limited by
the tightness of the screw connection which connects the
clamping pin to the pallet coupling or device. This is why only
screws of strength class 12.9 may be used.

Calculation of Permissible Transport Load
The robot coupling is limited to a maximum permissible torque at
the coupling interface. The dynamic load when using the robot
system for handling results in acceleration and deceleration forces
that have to be taken into consideration for the transport load.
To operate the robot coupling with dynamic handling, it is
essential for the maximum acceleration of the machine to be
known.
The acceleration has an effect even in the case of an abrupt
deceleration e.g. when the emergency stop switch is actuated.
Inclusion of the acceleration values is of crucial importance for
the operational safety of the robot coupling and the entire robot
and palletizing system. If it is not taken into account, this can
result in accidents and damage to the clamping system.
Calculation example to determine permissible transport load
Missing information or specifications can be requested from the
manufacturer.

Determination of formula values:
mpallet coupling, type: PKL mini 100 (aluminum) = 0.1 kg
mclamping pallet, type: PAL A 399 x 159 (aluminum) = 0.5 kg
mtransport load = 9 kg (example value)
I = 60 mm = 0.06 m (example value)
Calculating the acceleration force:
Maximum permissible torque for NSR micro 60: M = 15 Nm
Result of calculation:
Taking into account the robot acceleration, the lever arm, and the
handling mass, the load in the calculation example is permissible.
For every change to the technical data, a calculation must be
performed.

General assembly notes
If you wish to install the unit yourself, please request our
drawing.
NOTE
When connecting the robot coupling, please make sure that a
complete deaeration of the piston area during the locking
operation is possible through the air ports. Therefore, valves or
stop valves for deaeration should be available. If the turbo
connection will not be used, it must be possible that the relevant
piston side can be deaerated. If the pneumatic port for turbo
effect should not be used, the concerned piston side must have to
possibility to deaerate itself.
When uncoupling the air hoses the corresponding openings have
to be sealed with sealing plugs in order to prevent ingress of dirt
or coolant into the module.
If a coupling interface consists of 2 linked robot couplings, make
sure that the flatness and height deviation of the locating surface
from module to module (based on a gauge of 100 mm) lies within
0.01 mm. If several units are activated via shared hose lines,
supply cables with the following minimum cross-sections must be
used.

Mounting and Connection
Request our installation drawings if doing the installation
yourself.
The NSR micro 60 is fixed in place with 5 M3 screws.
Two mounting screws are used as fitting screws for positioning the
robot coupling precisely on the necessary robot flange. Precise
alignment and positioning of the robot coupling requires that the
fitting bores Ø 4 H7 on the opposite side are precisely positioned
in the mounting position.
NOTE
If the robot coupling is to be operated with monitoring of the
piston position, a recess for the sensors (MMS 22) must be
provided in the customer-specific robot flange, as these protrude
beyond the module at the base(11, Page 50).
