Drive voltage for the motor and the operating voltage for the magnetic bear-
ing are supplied by the MAG.DRIVE iM frequency converter. It also handles
the automatic monitoring of these systems.
The converter monitors continously all important operating parameters and
provides warning and alarm signals in case the operating conditions exceed
the specification or the set threshold.
Switching the motor to the generator mode keeps the magnetic bearing unit
in operation even in case of a mains power failure.
The frequency converter has the following interfaces:
■
a Profibus or another optional interface, see Section 4.2
■
an interface for the Leybold Service (RS 232) and
■
three connections for accessories, e.g. valves.
1.2 Supplied equipment
The pumps are shipped sealed in a PE bag with a desiccant to absorb mois-
ture.The maximum useful life of the desiccant is one year.
The forevacuum flange is capped with a protective cap. The purge gas and
venting flange is blank-flanged with centering ring with FPM sealing ring and
a clamping yoke.
The high-vacuum connection elements are not part of the standard
equipment. An inlet screen has been built in.
A mains mating connector for the frequency converter side (IP 54) is sup-
plied. A cable and a mains plug are not part of the standard equipment.
