13.3 Speed Chart for LIK Series
13.3.1 LIK Series with Op-Amp
The maximum attainable traversing speed of the encoder is determined by the maximum output
frequency of the interpolator and/or the maximum counting frequency of the operator‘s evaluation
electronics (e.g. controller or display).
Please take the suitable values for your application from the following charts and enter it into the
corresponding place (for “X”) 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 maximum scanning frequency of the encoder amounts to 200 kHz standardly, hence the maximum
attainable traversing speed will be derived from that� The op-amp decouples parasitic frequencies
and improves the interference immunity of the encoder under unfavorable conditions� The encoders
from NUMERIK JENA are available without op-amp also� Thus it is possible to increase the scanning
frequency which consequently enables higher traversing speeds up to 10 m/s�
The listed values in the charts refer to a grating period (TP) of 20 µm.
