BAUMULLER b maXX softdrivePLC - Intelligence in the drive

b maXX softdrivePLC - Intelligence in the drive

With the new b maXX softdrivePLC, Baumüller has made separate control hardware unnecessary for certain applications. By combining motion control and PLC functions in the controller, Baumüller has created a decentralized control architecture for programming in accordance with IEC 61131. making it extremely easy to set up distributed intelligence in the machine.

Without complicated tools for control programming, control tasks ranging from the simple calculation of digital inputs to highly complex control algorithms can be implemented in a decentralized way in the controller – tasks made easy by the ProDrive parameterization tool. The b maXX softdrivePLC runs as part of the firmware in the Baumüller drive concepts b maXX 6000. b maXX 5000 and b maXX 3300 and is suitable for single and double-axis applications.

b maXX-drivePLC: One of the fastest in-drive PLCs worldwide

With a cycle time of 100 μs for 1000 lines of STL, the b maxx-drivePLC is suitable for both extensive control and demanding motion control tasks. This means that by using our PLC, the control PLC can be relieved, downsized or even completely replaced. The clean decoupling of motion control applications from the machine program also creates a new level of transparency and clarity in the application.

Programming via ProDrive

By using softdrivePLC, you no longer need complicated tools for control programming. Control tasks can easily be implemented in a decentralized way in the controller via the ProDrive parameterization tool – from simple calculation to highly complex control algorithms.

Industry 4.0: Intelligent drives function as a data/sensor hub

With the Baumüller SmartValue function, data is collected directly in the process via the intelligent sensor/actuator level, preprocessed with the help of AI and other tools, and then used to optimize the machine. Data available in the servo drive, such as power, current, torque, speed or position, are thus used intelligently - to record the current utilization of the motor-drive combination, for example. In this case, the servo drive acts as a data hub. If the available data is not sufficient, the drive and also the motor with external sensors can easily be used as a sensor hub.

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

Single-cable solution for power and feedback systems

The single cable technology that can be fitted in Baumüller motors saves the user from having to use a feedback cable, which is usually required in addition to the obligatory motor cable. The result is a significant cost savings, as this eliminates the need for additional cables for encoder evaluation.
