SPEED CONTROL TYPE FUNCTION BLOCKS
 An external error or malfunction deriving from encoder/proximity or its wiring, does not necessarily involve
a change of safety status of the normal output (i.e. “Zero”) of the function block.
 Failures or malfunctions of encoder/proximity switch or its wiring are then recognized by the module,
managed and specified via the diagnostic bit on every function block (“Enable Error Out”)
 To ensure the safety features the diagnostic bit has to be used in the configuration program created by the user
to cause a possible deactivation of the outputs if the axis is working. In absence of encoder/proximity external
anomalies, Error bit will be equal to 0 (zero)
In presence of encoder/proximity external anomalies, error_out bit will be equal to 1 (one):
- Absence of encoder or proximity
- Absence of one or more wiring from encoder / proximity
- Absence of encoder power supply (only model with TTL external power supply)
- Error of congruence frequencies between signals from encoder/proximity
- Phase error between signals from the encoder or duty cycle error of a single phase
