The development/laboratory test stand for motor spindles is used to test dynamic loads and perform extensive long-term testing. The testing process is controlled by means of a modular software architecture that is visualised on two monitors. Testing processes can be individually programmed and customised by the user.

Software for spindle test stands

The test-stand software is a Windows-based solution that is programmed in-house and optimised for the respective test task. As the interface to the user, the uncomplicated user interface provides intuitive access to all functions of the test stand. Moreover, both the connection of the test stand to the customer's conveyor systems as well as its integration into the existing network environment is taken into account. This enables the data acquired to be processed and evaluated independently of the test stand.

Data recording

  • Analogue data
  • Digital data (SSI etc.)
  • CAN data (with synchronisation to analogue data)

Data storage

  • Data export as a text file (.csv), DIADEM file
  • Database connection ODBC, MS Access, SQL Server

Creating and editing test programs

  • Generation or import of test program data records
  • Editing program sequences
  • Evaluation within the sequences
  • Free adaptation of test sequences
  • On-line graphic of recorded data
