PROXIMITY INPUT FOR SPEED CONTROLLER MV
When an axis of the MV modules is configured for a measurement with two proximity
switches, these can be configured in interleaved mode. Under the conditions listed below
the system reaches a Performance Level = PLe:
Proximity switches must be fitted such that the recorded signals overlap.
Proximity switches must be fitted such that at least one is always activated.

In addition:
The proximity switches must be PNP type.
The proximity switches must be NO type (Output ON when detecting metal).
With the above conditions fulfilled, the DC value is equal to 90%.
The two proximity switches must be of the same model, with MTTF > 70 years.
