5.2.3. Speed/Position measuring system
• The basic version of the lift machines is equipped with an ECN 413 SineCosine encoder from Heidenhain
GmbH. The encoder is connected via a 17-pole signal plug connector fitted to the measuring system housing.
• Alternatively, the machines can be equipped with ERN 487 encoders (also from Heidenhain GmbH). We can
also provide other measuring systems on request.
• Use a shielded cable to connect the measuring system to the inverter system. We recommend the use of our
cable sets, which can be supplied as an accessory.
CAUTION
The measuring system of WSG lift machines with a
synchronous motor (WSG) is matched to the associat-
ed converter. Do not change the adjustment, as this
may make it impossible to use the motor. On the
measuring system housing there is a label showing
the "offset angle" determined at the factory.
This value depends on the converter used.
