Outdated DC Drive System

Is it possible to update a DC drive system without updating an old PLC & HMI control platform?


The customer had an outdated DC Drive System on their Tandem manufacturing lines.

Complicating the issue was an old Siemens PLC & HMI control platform that the customer did not want to upgrade. ICS was asked to perform a field upgrade on the old system.


Turnkey upgrade (mechanical, electrical & controls) of complete Tandem line was installed and started up in less than 1 week.

  • ICS performed upgrade during weekend / Holiday timeframe to help reduce downtime.
  • New AC Drive Technology was installed on 3 extruders.
  • Open loop vector technology used on extruders.
  • PLC and HMI code was rewritten and saved for customer backups.
  • New AC motors replaced old DC motors.
  • Regenerative AC Drive installed on Capstan.
  • Regenerative AC Drive installed on Coiler.
