1. Number of revolutions When entering the parameterization data make sure the parameters Measuring length in increments and Number of increments per revolution are chosen so that the quotient of the two parameters is a second power If this is not the case the encoder will correct the measuring length in increments to the next smallest second power in revolutions The number of increments per revolution remains constant The re calculated measuring length in increments can be read out via the extended diagnostic information for Class 2 and is always smaller than the predefined measuring length Therefore it can be that the actually needed total increment number is exceeded and the encoder generates a zero point changeover before reaching the maximum mechanical displacement distance Since the internal absolute position before the encoder was scaled and a zero point adjustment was executed recurs periodically after 4096 revolutions at rotating applications endless driving to the same direction the number of revolutions is not a power of two it comes inevitably to offsets For such applications one of the TR nominal configurations has to be used Operator input TR Electronic GmbH 2011 All Rights Reserved Printed in the Federal Republic of Germany Page 26 of 39 TR ECE BA GB 0032 00 09 19 2011 Relectron ic Device description start up 3 8 3 2 Nominal configurati2.
