MC_ChangeDataset - Example
The figure below shows the encoder changeover as a typical application of
the"MC_ChangeDataset" technology function.
A steel profile produced in the form of infinite material is to be cut to equal lengths
in a processing machine. AN additional machine encoder with measuring wheel is
installed in order to reduce slip of the feed rollers.
The measuring wheel does not return a position value at the time a new steel
profile is fed into the machine; positioning must therefore rely on the motor
encoder. A sensor is used to register the position at which the measuring wheel
detects the position of the steel profile. The sensor signal is then used with
"MC_ChangeDataset" to change over from the motor encoder to the machine
encoder (with or without encoder calibration, as required.) After the encoder
changeover, the steel profile can be fed precisely for further processing in position-
controlled operations.
