Characteristics of the Q0 Reflex Outputs
(Original Document)
General
Each positioning channel has an output controlled by the processor and which allows the integrated command from an ordered axis function to be performed. For example, a brake command between two shifts, safety etc. This output is static, the shared load is at 0 V of the sensor/pre-sensor voltage.
The output is protected against overloads and short circuits and in case of fault, information is made available to the processor about it.
