Actual percentage value 0 ...+10 V
7.8.5 Configuration 430 – Sensorless Field-Oriented Control, speed and
torque controlled
Configuration 430 extends the functionality of the sensorless field-oriented control of Configuration
410 by a Torque Controller. The reference torque is represented as a percentage and it is transmitted
into the corresponding operational performance of the application. Change-over between variable-
speed control and torque-dependent control is done jerk-free during operation.
Voltage output +20 V or input for
external power supply DC 24 V
