4.1 Electrical Installation of Controller
4.1.1 Overview
The LPC-600 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 23 shows the interfaces of the standalone controller LPC-600.1-01 with stand-alone
and minimal PLC functions. Figure 24 shows the interfaces of the LPC-600.2-01 controller with extended
PLC functions and USB interface for communication.

Interface (as labeled)
Description
1
“SENSORIC”
Position, field and temperature sensor signals from motor
Torque spec. for tightening of connector screws: Min. = 0.4, Max. = 0.6 Nm
2
“USER INTERFACE”
1 Digital Input
- Galvanic isolation with optocoupler
- Lowest input voltage for high level detection: min. 5 V

- Highest input voltage for low level detection: max. 0.8 V
- Minimum input resistance: R
IN
= 2.2 k
1 Digital Output
- Galvanic isolation with relay
- Relay: 1A / 30VDC, 0.3A / 125 VAC
1 Analoge Input
- Analog current input: 4 – 20 mA

1
Torque spec. for tightening of connector screws on motor side: Min. = 0.5 Nm, Max. = 0.6 Nm
4
“POWER INPUT”
DC power input -> 48V.
1
Torque spec. for tightening of connector screws on motor side: Min. = 0.5 Nm, Max. = 0.6 Nm
5
“Power on” Green LED
LED is on if supply voltage of signal electronics is present.
6
“Power Output not active”
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.
7
“RESET” Button
Reset button of the controller stage. The button is sunk mounted and can be activated for example with a
small screw driver.
8
2-Digit Display “Speed”
Rotational speed display in 100rpm
9
“UP” Button
Button for speed increasing and enabling of levitation
10
“DOWN” Button
Button for speed decreasing and disabling of levitation
11
“Firmware” Label
Firmware version and revision number
