• The client has a "Hot Stretch Line" with 1 SIMOVERT MASTERDRIVES rectifier and 9 SIMOVERT MASTERDRIVES drives. Because the series is obsolete in 2020, the client wishes to retrofit these drives to SINAMICS S120.
• The client has a shutdown of 2 weeks in the summer, so the migration needs to be done in this time frame.
• To make the client's mind better, we did the retrofit of 1 inverter during a normal weekend shutdown. With this way the client got confidence in the whole migration.

Siemens service experts delivered, installed and commissioned the new SINAMICS S120 drives (1 BLM; 9 SMM) . 
Challenges:

• Delivery time of the necessary materials
• Executing the installation and the commissioning during the shutdown of 2 weeks
• The line regulation is controlled in the S7 PLC above the drives. Some fine tuning of the drive regulations was still needed.
