4.3 Electronic drive unit
The magnetically levitated pump with integrated electronic drive unit is intended to be installed into and
controlled by the equipment.
As standard, the electronic drive unit is equipped with an
RS-232/RS-485
serial link interface and
RE-
MOTE
connector. It can also be controlled with the hand-held remote
HHR
available as an accessory
(see chapter "Accessories").
Depending on the ordering guide, the integrated electronic drive unit is equipped with an interface that
allows control through
EtherCAT, Profibus
control networks.
In this document, only the operations with the
Remote, RS-232/RS-485
and
HHR
interfaces are descri-
bed.
For the other interfaces, please refer to the operating manual of the control interface installed on
the pump
(see chapter “Applicable documents”).
The electronic drive unit does not power the pump.
Power supply comes from an external 48 VDC
unit
.
Regardless of the product’s configuration,
the control interface
of the electronic drive unit enables a
connection to the control network and display of the pump's operating status.
The integrated electronic drive unit makes it possible to:
● power the turbomolecular pump when it is connected to the external power supply
● power and control the water solenoid valve and heating (MT version pump)
