Drive System Retrofit for MasterDrives

Because of their superior functionality, comprehensive performance range and application flexibility, the Siemens Simovert MASTERDRIVES in CUVC, CUMC, Compact form and other variants has been a very successful drive system for single motor and multi-motor applications. The established common DC bus system enabled it to be used on demanding production machine processes across a wide range of industry sectors.

All good things must come to an end, but that doesn’t mean the end of the line for your production machine.

Optima’s innovative approach to upgrades significantly reduces the installation time and minimises risk to your site. All of our systems are thoroughly tested before they are shipped to site, completely eliminating any “out of box” failures.

Some of the benefits you will realise are:

  • Extended life span of your machine and increased availability due to continued spare parts supply with full support by Siemens
  • Improved productivity through lower energy costs and faster production cycles, through:
    • Simple operation monitoring using operator panel
    • User-friendly diagnostics with the STARTER tool
    • Additional interface options via PROFINET or PROFIBUS
  • Future-proofed due to access to the new world of TIA Portal

Optima’s approach for upgrades is to:

  1. 1.Analysis of your current machine configuration and potential further customer request
  2. Recommendation on the best replacement scenario
  3. Installation, configuration and commissioning of new  components and creation of circuit diagram and documentation
  4. Acceptance test and machine handover.

If requested, we can also provide training for all your relevant engineers and instruction of the operating personnel
