Inserting And Specifying A Motor Module - Siemens SINAMICS S120 Commissioning Manual

Vector control features
The motor connected to a vector control is simulated in a vector model based on data from the
equivalent circuit diagram. The motor module is emulated as precisely as possible to obtain the
best results regarding control control accuracy and control quality.
There are 2 types of vector control:
• Vector control without encoder (SLVC) as frequency control
• Vector control with encoder as speed-torque control with speed feedback
The vector control is characterized by the following features:
• Normal computing speed
• Best speed accuracy
• Best speed ripple
• Best torque accuracy
• Best torque ripple
• Operation with / without encoder
Vector control operation is possible both with or without an actual speed value encoder.
