Responsibility
Electronic devices are fundamentally not fail-safe. The company setting up and/or
operating the machine or system is itself responsible for ensuring that the drive is
rendered safe if the device fails.
IEC/EN 60204-1: "Safety of machinery - Electrical equipment of machines - Part 1:
General requirements" in the category "Electrical equipment of machines" sets out
safety requirements for electrical controls. They are intended to protect personnel and
machinery, and to maintain the function capability of the machine or system concerned,
and must be observed.
The function of an emergency stop system does not necessarily have to cut the power
supply to the drive. To protect against danger, it may be more beneficial to maintain
individual drives in operation or to initiate specific safety sequences. Execution of
the emergency off measure is assessed by means of a risk analysis of the machine
or plant, including the electrical equipment to EN ISO 12100: "Safety of machinery -
General principles for design - Risk assessment and risk reduction", and is determined
with selection of the circuit category in accordance with EN ISO 13849-1: "Safety of
machinery - Safety-related parts of control systems - Part 1: General principles for
design" (formerly DIN EN 954-1).
