Directive
To be considered when using electric devices of a rated
voltage between 50 and 1.000 V AC and between 75 and
1.500 V DC.
Electro-Magnetic
Compatibility
(EMC)
Definition according to the EMC regulations:
"EMC is the ability of a device to function in a satisfactory
way in an electro-magnetic environment without causing
electromagnetic disturbances itself, which would be
unbearable for other devices in this environment."

ESD Electro Static Discharge
Hazard analysis Extract from the Machinery Directive 98/37/EC:
The manufacturer is under an obligation to assess the
hazards in order to identify all of those which apply to his
machine; he must then design and construct it taking
account of his assessment.
Hardware enable Before the axis can be started up by software enable,
hardware or pulse enable has to be active. This means that
a high signal (24 V) has to be connected to the enable input
or inputs (restart lockout).
HIPERFACE High Performance Interface
HIPERFACE designates a sensor-transducer system by
Sick / Stegmann. The SinCos motor feedback system with
the standardized HIPERFACE interface is often used in
digital drive technology. Unlike the resolver, the SinCos
motor feedback system with HIPERFACE interface contains
electronic components. Over several motor rotations, a
HIPERFACE will report the absolute position values; this
cannot be performed by a resolver. A HIPERFACE is far
more precise than a resolver, but also more expensive.
