5.4 Fixing the Load
You have two options for fixing the load:

The load is fixed to the XYZ mounting platform.

The XYZ mounting platform is removed, and a fiber holder (e.g. F-603.41) is mounted
directly to the mounting interfaces of the P-616.
NOTICE
Mechanical overload due to too high torques and high loads!
High torques when fixing the load, as well as high loads, can overload the XYZ mounting
platform of the P-616. Mechanical overload can damage the piezo actuators, sensors, and
flexures of the P-616 and lead to loss of accuracy.

When fixing the load, do not exceed the following values :
−
Maximum torque 0.4 Nm
− Maximum push force capacity 15 N

Take into account the influence of the fixed load. For example, if a load of 0.5kg is fixed to
the P-616, a weight force of 5 N acts vertically on the P-616. This reduces the maximum
push force capacity in Z by N to 10 N.

When removing the XYZ mounting platform, when you loosen the screws hold onto it
tightly to avoid an excessive torque to the flexures.
NOTICE
Warping the P-616 when fixing loads with an uneven contact surface!
Fixing loads with an uneven contact surface could warp the P-616. Warping reduces the
accuracy.

Fix loads on the P-616 only when the surface contacting the P-616's platform has a flatness
of at least 100 μm.

For applications with large temperature changes:
Fix loads to the P-616 only when they have the same or similar thermal expansion
properties as the P-616.
NOTICE
Center of load at unsuitable position!
If the center of the load is located far away from the center of the motion platform (e.g. , tall
load and unwanted lever effect), the P-616 can, especially in dynamic operation, be damaged
by the high strain on the flexure guides, high torques and oscillations.

If the center of the load to be fixed is too high or to the side of the motion platform, adjust
the controller settings before startup or contact our customer service department (p. 37).

Respect the leverage effect of the fiber holder.

Ensure sufficient strain relief of the connected fibers.
