Function and design of the
MAG.DRIVE
digital
The MAG.DRIVE
digital
electronic converter is used to drive the MAG pumps
from MAG 830 to MAG 3200.
The electronic converter converts the single-phase line supply voltage into
a three-phase DC voltage to control and monitor the electronically-com-
mutated DC motor. It also evaluates measured signals and controls (open-
loop and closed-loop) the pump functions.
The temperature management system (TMS) and the magnetic bearing
control system are integrated into the converter. The TMS regulates the
pump temperature by switching the heating on/off or cooling the pump.
The digital magnetic bearing control system actively controls the pump
rotor in five axes (closed-loop control).
All parameters required for pump operation and the listed faults and ope-
rating hours are stored in a non-volatile memory in the pump. When the
converter is switched on, the data are loaded into the converter from the
pump.
The outputs of the electronic converter are no-load and short-circuit proof.
For remote control via control connector X14 we recommend that either a
relay or optocoupler is used to provide electrical decoupling.
Housing
The converter is supplied with a closed housing. It can be installed in a 19”
cabinet; see Section 2.7.
Front panel
Main switch
9-pin connecting socket for the plug-in control or for connection of a serial
interface
2 short-stroke keys
1 green/red STATUS LED
1 green COM LED (communications interface)
1 green MAIN LED (line supply voltage)
2 fuses TMS
The optional plug-in control has 10 keys and 1 LCD with 2 lines, each 16
characters. The plug-in control displays operating statuses and failures and
allows the configuration of the pumping system.
