Terminal assignment and commissioning 6.
6.1 Mechanical mounting
Shaft encoders
 Mount encoder housing by help of the mounting holes and three screws (square flange: 4 screws)
provided at flange. Observe thread diameter and depth.
 There is an alternative mounting option in any angular position by eccentric fixings, see under
accessories.
 Connect drive shaft and encoder shaft by using an appropriate coupling. The shaft ends must not touch
each other. The coupling must equalize any shifts due to temperature as well as mechanical tolerances.
Observe the maximum permitted axial or radial shaft load. For appropriate couplings please refer to
accessories.
 Tighten the mounting screws firmly.
Hollow shaft encoder
 Clamping ring fixture
Prior to mounting the encoder open the clamping ring completely. Push encoder onto the drive shaft and
tighten the clamping ring firmly.
 Encoder torque pin
Slide encoder onto the drive shaft and insert torque pin into the adjusting element provided by customer.
 Adjusting element with rubberized spring element
Push the encoder on to the drive shaft and insert the parallel pin into the mounted adjusting element (not
supplied) (with rubberized spring element)
 Adjusting bracket
Push the encoder over the drive shaft. Insert the adjusting bracket into the rubberized spring element of
the encoder and fasten the adjusting bracket on the contact surface (not supplied).
 Shoulder screw
Push the encoder over the drive shaft and insert the shoulder screw (not supplied) in the rubberized spring
element of the encoder.
 Coupling spring
Mount the coupling spring with screws onto the fixing holes of the encoder housing.
Push the encoder over the drive shaft and fasten the coupling spring on the contact surface.
6.2 Electrical connection
Assignment – M12 connector
Follow also the instructions of the respective supplier.
- Press mating connector softly into the plug.
- Turn mating connector carefully until the code mark is interlocking the corresponding space provided by the
plug. Insert bushing completely. Tighten the nut as far as possible.
Exchange bus cover
The bus cover is to be stored and transported whilst in the ESD bag only. The bus cover has to fit the case
tightly and has to be firmly secured by screws.
Remove bus cover
- Unscrew both fixing screws of the bus cover.
- Loosen bus cover carefully and remove it in axial direction.
Plug on bus cover
- Plug the bus cover carefully onto the D-SUB plug of the basic encoder, then push it over the rubber seal.
Avoid the case getting wedged. The bus cover has to fit tightly the basic encoder.
- Tighten both fixing screws firmly and conformable.
- An optimized connection between encoder case and the braiding shield of the supply cable is only achieved
by a complete and close fit of the bus cover onto the basic encoder (interlock).
