Safety

Definition : the mastering of risk and the suppression of unacceptable risks

A risk is the combination of the probability of damage caused by a situation, and the
extent of that damage

Differences EN954-1 / IEC/EN61508-1

Differences EN954-1 / IEC/EN61508-1

EN954-1 (type A) : Safety norm with deterministic nature based on the architecture and
the redundancy of safety circuits

IEC/EN 61508 (type B) : Safety norm with probability nature based on the architecture
and the reliability of the systems witch guaranty the safety. The safety integrity levels
(SIL) are defined there.

The IEC/EN 61508 provides complementary requirements to the EN954-1

After the global evaluation of the risk level,
you have to choose the safety solution that
complies with the advocated category for your

This schematics could be used for
machine with a long stopping time in
freewheel (high inertia machines).
This schematics should not be used
for hoisting applications. When a safe
condition is required, the deceleration
of the motor is requested first. After
a temporization that corresponds to
the stopping time (or longer), the
