Danger of death, serious physical injury and/or damage to property
due to deactivation of safety functions, caused by an unstable shaft
drive!
 The system manufacturer must implement suitable design measures, so
that the drive of the measuring system is ensured at all times through
the shaft and mounting of the measuring system (fault exclusion). The
specifications of DIN EN 61800-5-2:2008 "Adjustable speed electrical
power drive systems, Safety requirements - Functional, Table D.16 –
Motion and position sensors" must be observed.
 In general, the requirements and acceptance conditions for the
complete system must be taken into account for mounting.
As the installation situation is application-dependent, the following
notes are not exhaustive.
 The measuring system must be installed on a grease-free shaft.
 Axial slipping of the measuring system on the drive shaft must be
prevented by the fixing of the clamping ring, see Figure 4.
 Further measures may be required to prevent axial slipping of the
measuring system.
 The clamping of the measuring system must not be axially loaded.
 The screw of the clamping ring must be tightened with 3 Nm using a
torque wrench.
 The screw must be secured against unintentional loosening.
 Radial slipping of the measuring system on the drive shaft must be
prevented by means of form closure, using a parallel key / groove
combination; the measuring system must be fixed on the side of the
drive using a dowel pin, see Figure 5.
 In case of applications with low ambient temperatures, increased values
for the start-up torque result. This fact is to be considered when the
assembling and wave drive is performed.
