Hi, whilst I have never needed to do this, I don't see any elevated risks associated with at least trying it, given the drives equivalent power rating, then there should be no additional load on the rectifier However: 1: ENSURE that the AC connections are adequately shielded and 2. ENSURE that you perform the capacitor reform for the "new" AC drive - see chapter 12 here: Operating Instructions Frequency Converter (AC-AC) Compact Type Whilst this procedure requires the building of a circuit, there are suitable and easier alternatives, You can invoke the rectifier to perform this function for you, or you can apply 3 phase power as per section 14.2 of this Sinamics procedure S120 Booksize Power Units To my knowledge, the Masterdrive AC input phases do not appear to be directly measured, the drive does however, monitor the quality of the DC Link in terms of amplitude and ripple. If these are transgressed, then you may well receive Input phase missing type faults etc Regards, Graeme |
