In plastic injection molding, we often encounter products from the manufacturer B&R (ABB has owned B&R since 2017): the old Acopos 1045, 1090, 1022, 1016 servo drives and the newer ones: the Multis.
Multik still has sales support from the manufacturer at the time of writing (December 2015), but end users must purchase older 10xx drive modules from alternative sources: repair companies and dealers.
Many repair companies claim to be able to repair these modules. Many do, with varying degrees of success. Performing the repair is one thing, and it can be successful or unsuccessful.
Sometimes it happens the first time, but sometimes it only happens the second/third time.
This means 2x/3x the shipping costs, lost production and nervousness, not to mention the reputation of the repair company. Often the full test can only be performed after the return, installed, in a machine environment. This is when the maintenance staff is faced with the original or possible new error.
Therefore, it is of utmost importance that after repair, the servos are placed in a test environment, right at the repair point, where they can be actually tested by simulating the machine environment/settings.
The picture shows our B&R, Acopos testbed, which allows us to fully test both the Acopos 10xx and Multi servo drives. This allows us to provide a 2-year warranty on repairs/refurbishments.
You can also send your drive for a test if you are unsure. Or if you do not have information about the module's condition. We will calculate a test price for you.
