6.7.1 Configuration 110 – Sensorless Control
Configuration 110 contains the functions for variable-speed control of a 3-phase ma-
chine in a wide range of standard applications. The motor speed is set according to
the selected ratio of the reference frequency to the necessary voltage.
Voltage output +20 V or input for
external power supply DC 24 V
GND 20 V/ GND 24 V (ext.)
Digital input STOA (1st shutdown
path of safety function STO)
Start of clockwise operation
Start of anticlockwise operation
Digital input STOB (2
nd
shutdown
path of safety function STO)
Analog signal of actual frequency
Supply voltage +10V for reference
value potentiometer
Reference speed 0 ...+10 V
6.7.2 Configuration 111 – Sensorless Control with Technology Controller
Configuration 111 extends the functionality of the sensorless control by software
functions for easier adaptation to the customer's requirements in different applica-
tions. The Technology Controller enables flow rate, pressure, level or speed control.
Voltage output +20 V or input for
external power supply DC 24 V
GND 20 V/ GND 24 V (ext.)
Digital input STOA (1st shutdown
path of safety function STO)
Fixed percentage value change-
