6.6 Wiring the SYNC/Device Ready digital output
The SYNC/Device Ready digital output is used to issue an error and a regular index
pulse.
The structure and wiring principle of the digital output are shown below.

If an inductive load is present: Provide an arc-suppression circuit at the digital switching
output. Attach a freewheeling diode directly to the load for this purpose.
Switching behavior PNP switching against supply voltage UV
Resting level: High (device ready)
working level: Low (error), low pulse (15 Hz, index, corresponds to meas‐
urement at 90°)
Features Short-circuit protected and temperature protected

Longer connecting cables at the digital output of the device should be avoided due to
the resulting fall in voltage. This is calculated as follows:
Δ U = (2 x length x current) : (conductance value x cross-section)
Conductance value for copper: 56 m/Ω mm
