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).
