That said, the replacement drive is also totally obsolete. Using the Drivemonitor software, it is possible to take the backup of your existing drive and convert it to operate on the newer hardware/firmware and this works fine (most of the time ) Regards, Graeme

Masterdrive series drives are phaded out & new Sinamics series is available for replacement. Since its newer digital series, you can get the complete latest compatible package suitable to your application. HTH
