Speed Chart for LIKgo Series
The maximum attainable traversing speed of the encoder is determined by the maximum
output frequency of the interpolator and/or the minimum counting frequency of the operator‘s
evaluation electronics (e.g. controller or display).
Please take the suitable values for your application from the following chart and select it in the
ordering key� Pay attention to your chosen interpolation factor and the targeted traversing speed
first. If you have found the respective information, please check if your evaluation electronics is
able to achieve the needed counting frequency�
The listed values in the charts refer to a grating period (TP) of 20 µm.
