10 Loading capacity
Nominal torque can be exceeded statically up to the limit
torque. If the nominal torque is exceeded, additional
irregular loading is not permissible. This includes
longitudinal forces, lateral forces and bending moments.
Limit values can be found in chapter 14 “Specifications”,
on page 70.
10.1 Measuring dynamic torque
The torque flanges can be used to measure static and
dynamic torques. The following rule applies to the
measurement of dynamic torque:
S The T10F calibration made for static measurements is
also valid for dynamic torque measurements.
S The natural frequency f

for the mechanical
measuring system depends on the moments of inertia
J

and J
2
of the connected rotating masses and the
T10F torsional stiffness.

designated for the T10F, even under alternating load.
The vibration bandwidth must fall within the loading
