Dears,
We have two Control Techniques inverter drives at corrugator machine's stacker unit to control the operation of its plate form motor 30kw. The model is "Unidrive 3405-UNIDRIVE CLASSIC SERIES, with device-net module UD77". Unfortunately the production of this drive has been stopped for a long time by CT and there is no any spares for this drive available in market. We dont have in a position in this time to replace these drives with latest model as this is a very costly job. So do any one knows about any Ebay which could supply us the spare cards of this drive?
