HEIDENHAIN Angle Measurement – Authorised UK Distributor – Supply, Installation & Service
Angle Measurement using Angle Encoders
HEIDENHAIN Angle encoders are available in many different configurations from sealed integral bearings to modular utilising the rotary mechanical axis supplied on the machine tool. With angle measurement accuracy down to +/- 0.9″ (seconds) and line counts upto 180000, available in incremental and absolute signal format with various mechanical mounting from stub shaft, hollow bore, blind bore and modular almost any application is covered.
Angle Measurement using Rotary Encoders
HEIDENHAIN rotary encoders are used for many applications from linear measurement (mounted on motors, ballscrews and pulleys) to speed feed back and orientation feed back for spindle position. The angle measurement range is vast as requirements vary massively with mechanical fixings, line counts, cable length and connector requirements.
HEIDENHAIN Angle Measurement
Incremental angle and rotary encoders, by referencing the encoder scale the original datum point can be re-established simply enabling the operator to pick up where they left of after a power down situation. Referencing is a simple fast process with HEIDENHAIN world leading technology of distance-coded reference marks. The measuring step can be subdivided in the DRO display or subsequent electronics such as EXE/IBV box or TNC/CNC control for a wide range of resolutions. Incremental rotary encoders with commutation signals supply the angular shaft position value – without requiring previous traverse – with sufficient accuracy to correctly control the phases of the rotating field of a permanent-magnet three-phase motor.
Absolute angle and rotary encoders, do not require referencing with a bit code immediate feedback upon power up the axis position is known along with traverse range and alarm technology, making the Absolute encoder technology a requirement on most modern types of CNC machinery. The encoder transmits the absolute value through the EnDat interface/other types of serial interface along with an incremental track in some models.
Magnetic Modular Encoders, ERM magnetic modular encoders are suited for use in production machines, with their large inside diameters, small compact design and non contact scanning heads high speeds can be catered for with C axis of lathes, spindle speed and orientation on milling machines.
