4.1.2.7 Encoder with belt drive
The encoder in the encoder box (on the stator side) is coupled via a belt. This means, for
example, the hollow shaft can be used to route media. Gear ratio, see the table "Ratio" in
this Chapter.
Note
Only qualified personnel may replace a belt. To do this, a device is required to measure th
