Control Mode - Siemens SINAMICS S120 Commissioning Manual

Activating function modules
Proceed as follows to activate a function module:
1. Click on the desired function module (e.g. technology controller).
Repeat this step for all additional function modules that you wish to activate.
Note
When the "basic positioner" function module is activated, then the "position control" function
module is automatically activated as well.
2. Save the project to back up the settings.

Control mode

Overview
Closed-loop speed control (with and without encoder) and closed-loop torque control are
available for servo drives.
Speed control
The speed control of a variable-speed drive has the task of following the speed according to a
specified setpoint (reference variable) as precisely as possible and without overshoot.
Torque control
The torque control has the task of ensuring that the torque actual value tracks the torque
setpoint as precisely as possible, i.e. without any delay and with low associated ripple. For this
control mode, the torque is the command variable.
Requirements
• You have completely specified and configured the motor used in the device configuration of
the drive axis.
Note
This basic parameterization cannot be performed without having completed this full
configuration.
