Fieldbus systems

Controller functionalities

Encoder angle via field bus:

For motors with multiple windings, the encoder cable is operated without splitting.

Error response “Return motion in case of power supply failure”:

In the event of a power supply failure, the drive performs positioning to a parameterizable position, provided there is sufficient energy in the DC link.

» The advantage: Protection of the machine against uncontrolled coasting down and resulting damage

Master-slave coupling for load balancing:

This feature allows the load of two drives moving a load together to be shared in a defined ratio.

» The advantage: Smaller converter technology possible › Cost savings

Cogging torque compensation:

The cogging torque of synchronous motors influences the concentricity of the motors. Cogging torques are identified by means of automated measurement and an angle-dependent current is pre-controlled. This compensates for the cogging torque.

» The advantage: Improved concentricity of the motors, in particular at low speeds › Cost savings
