Rexroth has developed adaptive control modes for the Rexroth PS 6000 system to ensure total quality control.

Rexroth has also introduced the option of using electric or pneumatic servo drives for welding guns.

The UIR adaptive control system guarantees total control and documentation of spot welds.

For demanding material and metal combinations, Rexroth offers adaptive current/voltage control including monitoring functions for fully documented quality control.

The innovative current/voltage control displays all the process-critical parameters online in a diagram, enabling accurate inspection of the weld spots.

Rexroth’s resistance spot-welding control systems offer constant-current regulation, pressure regulation and the electrode-care concept including tip dressing.

The PS 6000 system features flexible scalability in terms of power and functionality.

An identical mechanical set-up gives the option of using alternating current and medium-frequency inverters.

The inverters boast a broad range of functions and can handle spot, projection and resistance seam welding.

The medium frequency inverters offer many additional functions for high-strength metals, aluminium and three-member joints.

The control system’s adaptive control modes provide supreme process reliability and communicate with the higher-level control system via standard field buses.

Rexroth has developed identically sized electric and pneumatic servo drives to control servo weld-guns in automotive welding and assembly lines.

By combining electronics and pneumatics, the intelligent control ensures high speed, gentle and bounce-free positioning, free position control and maximum repeat accuracy of the electrode force.

The electric servo motor lets users choose between identically sized servo pneumatic and servo electric drives for X-type robotic welding guns.

The servo-electric function module combines a servo motor with ball screw and separate electric balancing axis.

Integrating the drive control in the Rexroth welding control system provides the user with an optimum-compatibility system.

The BOS 6000 Windows user interface offers programming, monitoring and logging of the entire welding process, the quality module and the drive controls.
