Appendix B: Glossary
Analog A parameter, e.g. voltage, which can be adjusted
steplessly. 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® is the name of a feedback system
developed by Max Stegmann GmbH. The SinCos motor
feedback system with standardised HIPERFACE® is
often used in digital drive technology. In contrast with
the resolver, the SinCos motor feedback system with
HIPERFACE
®
contains electronic components.
Interference (lat. interferre - to carry in) Superposition of waves.
JetMove 208-480 JetMove 2xx identifies a product series of digital servo
amplifiers by Jetter AG. The extension represents the
following features:
– 208 identifies a rated current of 8 A;
– 480 identifies an operating voltage of max 480 V;
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 will be 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.
