Case study :

FPT

Besoin / Contexte

The machining centre is equipped with an obsolete 840C digital control system. - High failure rate, tedious and costly troubleshooting. - No spare parts.

Solutions

- Implementation of a solution based on the 840DSL digital control with conservation of existing drives and motors (611A and 1FT5).

Résultats

- Sustainability of the machining centre. - Competence of maintenance staff for this machine. - Easy troubleshooting thanks to the specific documentation developed. - Parts available and in stock. - Economic gain in relation to the machine manufacturer. - Optimisation of machining times.

Vallourec

Besoin / Contexte

- Ageing components of the analogue controls of a hot rolling mill. - Need to be able to change the power block in less than one hour. - Replacement of the DC rectifiers of the cages.

Solutions

- Production of rackable power blocks. - Integration of these power blocks with a DC Simoreg CM controller with a Profibus DP communication network. - "Customized" assembly with scaling of direct and reverse power bridges depending on the actual application, and of the tables depending on the available space. - Use of standard components that are easily accessible on the power electronics market.

Résultats

- Obsolescence management. - Components available on the market. - Standard, economical products, which are easy to maintain.
