Round axis functionality

The encoder supports the function for round axes. The steps per revolution are set as a
fraction. As a result, the total resolution does not have to be configured to 2ⁿ times the
resolution per revolution and can also be a decimal number (e.g. 12.5).

NOTE

The output position value is adjusted with the zero point correction, the counting
direction set and the gearbox parameters entered.

Example with transmission ratio

A rotating table for a filling system is to be controlled. The resolution per revolution
is predefined by the number of filling stations. There are nine filling stations. For the
precise measurement of the distance between two filling stations, 1,000 steps are
required.

Figure 3: Example position measurement on a rotating table with transmission ratio

The number of revolutions is predefined by the transmission ratio = 12.5 of the rotating
table gearing.

The total resolution is then 9 × 1,000 = 9,000 steps, to be realized in 12.5 revolutions
of the encoder. This ratio cannot be realized via the resolution per revolution and the
total resolution, as the total resolution is not 2ⁿ times the resolution per revolution.

The application problem can be solved using the round axis functionality. Here the
resolution per revolution is ignored. The total resolution as well as the nominator and
divisor for the number of revolutions are configured.

9,000 steps are configured as the total resolution.

For the nominator for the number of revolutions 125 is configured, 10 as the divisor
(125/10 = 12.5).

After 12.5 revolutions (that is after one complete revolution of the rotating table) the
encoder reaches the total resolution of 9,000.
