Simple technological tasks can be carried out by the SINAMICS S120 Control Unit itself. The CU320?2 Control Unit is available for multi-axis applications and the CU310?2 Control Unit for single drives.

Sophisticated Motion Control tasks are best supported by the powerful SIMOTION D Control Units (D410?2, D425?2, D435?2, D445?2, D455?2) with graded performance.

Each of these Control Units is based on an object-oriented SINAMICS S120 standard firmware which contains all the most popular V/f control modes and closed-loop control variants, that can be scaled to meet even the most advanced performance requirements.

The following are ready-to-configure drive objects (drive controls):

• The control for a line infeed:
  Infeed Control
• The control for the broad scope of rugged asynchronous (induction) motors and torque motors, including sensorless:
  Vector Control
• The control for permanent-magnet excited synchronous and servo asynchronous motors with demanding dynamic requirements:
  Servo Control

All these control variants are based on the principle of field-oriented, closed-loop vector control.

The most commonly used V/f control modes are stored in the Vector Control drive object and are ideal for implementing even simple applications such as, for example, group drives with SIEMOSYN motors.
