13.3.2 Incremental Encoder 2
13.3.2.1 General description
The incremental signals are transmitted as square-wave pulse trains A and B, phase-shifted by 90°
electrical. The signals A and B and their inverted signals typically have TTL levels.
13.3.2.2 EPOS2 Implementation
A second incremental encoder can be connected to the EPOS2’s digital inputs DigIN7 to DigIN9, the
same inputs which are used for «Master Encoder Mode» and «Step/Direction Mode». Therefore, this
two modes cannot be used in conjunction with the Incremental Encoder 2.
If the supply voltage of the incremental encoder is 5 V and the current is less than 150 mA, it can be
directly supplied from the +V AUX
signal (J5-9, respectively J5B-4). Otherwise, an external power supply
must be connected to power the sensor.
