We have noticed, that for some people it is not clear how our angle encoders work and how to make use of it. Here are some facts about them:
1) we use incremental encoders from AMS (AS5304A), absolute encoders are not possible in the current design,
2) in order to define the ZERO position for each DOF, we use a hall sensor, beeing placed in the middle of each angular freedom,
3) that means: each robolink system has to be “initialized”, whenever the power is switched on,
4) the resolution of the encoders are:
29 (polepairs) x 160 (signals) = 4.640 signals per 360° = 0,078° for all rotationg motions of the size RL-50,
31 (polepairs) x 160 (signals) = 4.960 signals per 360° = 0,073° for all pivoting motions of the size RL-50,
62 (polepairs) x 160 (signals) = 9.920 signals per 360° = 0,036° for all motions (rot AND piv.) of the size RL-90 (Base joint),
you can find more information in our current catalogue on page 18 or in our documentation on pages 10-12 (=> pdf download in the support&service area of the robolink homepage).
The FAQ list will be updated soon (it does currently not contain our new products).
