Appendix B: Glossary
Analog A parameter, e.g. voltage, which is steplessly
adjustable. Contrasted with digital.
Autotransformer Transformer without electrical isolation between
primary and secondary circuit.
Ballast resistor Resistor converting into heat the energy fed back to the
drive during rheostatic braking or braking operation.
Circuit-breaker A circuit-breaker without monitoring function. Also
known as automatic circuit-breaker.
DC link voltage DC circuit within a servo drive on the basis of which the
motor currents are generated.
Digital Presentation of a parameter, e.g. time, in the form of
characters or figures. This parameter in digital
representation can be changed in given steps only.
Contrasted with analog.
Electromagnetic
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."
Encoder A feedback element that converts linear or rotary
position (absolute or incremental) into a digital signal.
HIPERFACE HIPERFACE designates a sensor-encoder system by
SICK AG. The SinCos motor feedback system with the
standardised HIPERFACE interface is often used in
digital drive technology. Unlike the resolver, the SinCos
motor feedback system with the HIPERFACE interface
contains electronic components.
Interference (lat. interferre - to carry in) Superposition of waves.
JetMove 225-480 JetMove 2xx identifies a product series of digital servo
amplifiers by Jetter AG. The extension represents the
following features:
– 225 identifies a rated current of 25 A;
– 480 identifies an operating voltage of 480 V max.
Earth-leakage current
breaker A protection device that is monitoring whether the sum
of all currents flowing into a circuit and out of it is zero.
If the limit is exceeded, the circuit is de-energized.
Line filter A filter installed in the mains to suppress radio-
frequency interferences in the supply voltage.
Motor circuit-breaker A circuit-breaker with monitoring functions of phases
and temperature of a motor.
Primary circuit Incoming circuit of a transformer.
Process A program or a part of it. A related sequence of steps
carried out by a program.
