Results:

The decentralized Rexroth system architecture offers distributed control and drive intelligence: With the ideal interaction between the CNC control, IndraDrive M drives, and IndraDyn S motors, Weisser’s HOT system enables significantly higher workpiece speeds than traditional solutions. Yet, Rexroth’s control architecture offers even more advantages:

  • Handling of machines has become more comfortable and intuitive
  • Much faster set-up and changeover times
  • CNC control transmits up to 4,000 positions/sec to the drives
  • Maximum productivity and accuracy with cycle times of 250 microseconds
  • Consumes about 20 percent less energy
  • Consistent energy monitoring with IndraMotion MTX energy analyzer
