The Jetter system bus is a system-bus system of a
cable length of 200 m max. , and of fast data
transmission rates of 1 Mbit/s. In addition to this, the
Jetter system bus is highly immune to interferences.
Therefore, the Jetter system bus is suited to realise field
bus applications in a limited space.
Control technology comprising control systems, motion
systems, user interfaces, visualization devices, remote
I/Os and industrial PCs. Programming by means of
multitasking and a modern sequence-oriented
language. Communication by means of Ethernet TCP/
IP and making use of the Web technologies.
A circuit-breaker with monitoring functions of phases
and temperature of a motor.
Normal Null = Sea Level
Protective Earth: "Protective Earth", respectively
"Protective Earth Conductor"
Feedback unit at a servo motor for determining the
absolute position within one revolution. Other than a
HIPERFACE, the resolver will not provide any
information on how many revolutions the motor has
performed so far.
A resolver could be envisaged as a transformer; the
couplings of its secondary windings (sine and cosine)
change in relation to the position of the motor shaft.
Basically, a resolver consists of a rotor with one coil
(primary) and a stator with two coils (secondary). The
stator windings are displaced by 90° (sine and cosine).
The resolver itself does not contain any electronic
components.
Safe Extra Low Voltage:
Voltage, which, under all operating conditions will not
exceed a peak or DC voltage of 42.4 V. This voltage is
either measured between two conductors or between
one conductor and earth.
The circuit, in which this voltage occurs, must be
separated from the mains power supply by a safety
isolating transformer or some equivalent.
Type name of a plug-in connector
time rise / time hold: "rise time of a pulse / total hold
time of a pulse"
time rise/time normal: "rise time of a pulse / total
duration of a pulse"
Supply network which is solidly earthed in the neutral
point and which is equipped with a protective earth
conductor.
