JetMove D203 Appendix
Jetter AG 137
JetMove JetMove is the name of a series of digital servo amplifiers
produced by Jetter AG.
For example, JetMove D203, where
– D stands for "Dual", in the sense of controlling two motors
– 203 identifies a rated current of 3 A
Jetter system bus 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.
JetWeb Control technology comprising control systems, motion
systems, HMIs, 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.

Resolver 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 and a
stator with two coils. The stator windings are displaced by
90° (sine and cosine). The resolver itself does not contain
any electronic components.
SELV 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.
Software Enable A superordinated controller issues a software command to
enable an axis, which causes the motor to be energized.
Hardware enable (restart lockage) has to be there before
giving the software enable.
