Background
A PLC control system was needed for test rigs for gearbox systems which required high speed and high torque capabilities.
Customer expected
- precise synchronization of electrical motors for the test components
- data logging for each cycle to capture torque and speed value
Implementation
- Siemens S7 PLC with Sinamics Drives
- SCADA software for operator control
- Logged data in an external device for data access, retrieval and analysis
Outcome
- Improved gearbox testing capabilities both in terms of the high torque and speed requirements
- Analytical capability (data used to correlate actual road test results with gearbox test results)
- Cost savings through reduced power consumption
