8 Terminal assignment and commissioning

8.1 Mechanical mounting

Solid shaft encoders

Mount the encoder with the help of the mounting holes and three screws (square flange: 4 screws)

provided at the encoder 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 compensate temperature and mechanical backlash. Observe the maximum

permitted axial or radial shaft load. For appropriate couplings please refer to accessories.

Tighten the mounting screws firmly.

Blind hollow shaft encoders

Mounting by clamping ring: Prior to mounting the encoder open the clamping ring completely. Attach

encoder to the drive shaft and tighten the clamping ring firmly.

Mounting by adjusting element with rubber buffer: Attach the encoder to the drive shaft and insert the

cylindrical pin into the adjusting element with rubber buffer (provided by customer)

Spring washer: Fasten the spring washer at the mounting holes of the encoder housing using screws.

Attach the encoder to the drive shaft and fix the spring washer to the contact surface.

8.2 Electrical connection

Ever store and transport the bus cover in the ESD bag only. The bus cover must fully rest against the housing

and be firmly screwed together.

For electrical connection remove the bus cover as follows:

Release the fastening screws of the bus cover

Carefully loosen the bus cover and lift off in an axial direction

Carefully plug bus cover onto the D-SUB connector of the basic encoder. Slide it over the seal by

avoiding any cocking. The bus cover must fully rest on the basic encoder.

Tighten the fixing screws firmly and equally.

An optimum connection of encoder housing and bus cover will be only provided if the bus cover mounting

surface is fully resting on the basic encoder (positive locking).
