1.2 Intended use
MSD Servo Drives are components for installation into stationary electric systems or
machines.
When installed in machines the commissioning of the servo drive (i.e. start-up of
intended operation) is prohibited, unless it has been ascertained that the machine fully
complies with the provisions of the Machinery Directive 2006/42/EC; compliance with
EN 60204 is mandatory.
Commissioning (i.e. start-up of intended operation) is only permitted when strictly
complying with the EMC Directive (2004/108/EC).
The MSD Servo Drive DC-AC conforms to the Low Voltage Directive
2006/95/EC.
The DC-AC servo drives comply with the requirements of the harmonized product
standard EN 61800-5-1.
If the DC-AC servo drive is used for special applications, such as in areas subject to
explosion hazard, the required standards and regulations (e.g. in the Ex zone EN 50014,
“General provisions” and EN 50018 “Flameproof housing”) must always be observed.
Repairs may only be carried out by authorized repair workshops. Unauthorized opening
and incorrect intervention could lead to death, physical injury or material damage. The
warranty provided by Moog GmbH would thereby be rendered void.
NOTE:
Deployment of the DC-AC servo drives in non-stationary equipment is
classed as non-standard ambient conditions, and is permissible only by special
agreement.
1.3 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.
In the section on “Electrical equipment of machines” the standard EN 60204-1/
DIN VDE 113 “Safety of machines” stipulates 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 off 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 stop measure is assessed by means of a risk analysis of the machine or
plant, including the electrical equipment in accordance with EN ISO 14121 (previously
DIN EN 1050), and is determined in accordance with EN ISO 13849-1 (previously
EN 954-1), “Safety of machines - Safety-related parts of controls” by selecting the circuit
category.
