5.8 Rotational speed measuring system
The rotor is delivered as standard with a ring gear for the
rotational speed measuring system. The option is avail
able to fit the stator with a sensor head to scan the
mechanical increments (ring gear).

Important
The rotational speed measuring system uses a magnetic
measuring principle. In applications where high magnetic
field strengths can occur, e.g. eddy-current brakes, imple
ment suitable measures to ensure that the maximum per
missible magnetic field strength cannot be exceeded (see
Chapter 15 "Specifications", Page 64).
