4.1 Electrical Installation of Controller
4.1.1 Overview
The LPC-200 controllers have signal processor controlled power converters with switched inverters for the
drive and the bearing windings of the motor. The signal processor allows precise control of pump speed and
impeller position. Figure 20 shows the interfaces of the standalone controller LPC-200.1 with stand-alone
and minimal PLC functions and Figure 21 the interfaces of the LPC-200.2 controller with extended PLC
functions and USB interface for communication.

Interface (as labeled)
Description
1
“MOTOR”
- Position, field and temperature sensor signals from motor
- Drive and bearing currents of the motor
Torque spec. for tightening of connector screws: Min. = 0.4 Nm, Max. = 0.6 Nm
2
“USER INTERFACE”

- 450 Ohm shunt input
3
“POWER INPUT”
DC power input -> 24 - 48 V
4
“Power on” Green LED
LED is on if supply voltage of signal electronics is present.
5
“Power Output off”
Red LED
Red LED is off if the switched output stage of the controller is enabled. If the LED is on, the bearing and
drive coils of the motor carry no current.
