8LT torque motors are equipped with a magnetic or EnDat encoder. The encoder system is specified as part of the order number in the form of a 2-digit code (ee).
Magnetischer EnDat Geber
With the hollow-shaft motor variant (8LTB and 8LTK), EnDat 2.2 encoders (M0) with distance-coded absolute position are used.
Commissioning
When started for the first time, the motor does not detect its actual position. A shaft movement of ≤18° degrees is required for detection. Preferably in single-phase mode (stepper mode).
Drehrichtung
Hohlwellenmotoren (8LTB / 8LTK) weichen von der üblichen Drehrichtung (rechts) ab und werden linksdrehend ausgeliefert. Eine softwareseitige Anpassung auf rechtsdrehend ist durch den Anwender möglich.

Endat 2.2 Geber
For the advanced, fully digital EnDat 2.2 protocol, the positions are generated directly in the encoder and communicated serially with the drive system. This transfer is very robust in relation to disturbances and is even certified for safety applications.
EnDat 2.2 is therefore to be preferred over the older EnDat 2.1 variant.

All 8LT torque motors are available with a form A oil seal per DIN 3760.

Wartung
Damit die Funktion des Wellendichtringes auf Dauer gewährleistet ist, muss er regelmäßig mit Öl geschmiert werden. Ein nicht geschmierter Wellendichtring verhärtet durch die erhöhte Reibungswärme und kann dann nur noch die Funktion als Staubschutz auf Dauer gewährleisten.
Für eine ausreichende Schmierung des Wellendichtrings ist während der gesamten Lebensdauer des Motors zu sorgen.
Daher ist der Anbau eines Getriebes an Motoren mit Wellendichtring nicht zulässig!
