I have some Berger lahr drives in an EDM, the drives are old, MI 249810 5 phase drives, they have failed ( too old I was told,) and need repair or replacement (retrofit), the motors are fine they are Berger lahr RDM 51117/50. Would like to replace all with new drives and motors, dont believe I can get new drives that would work with old motors being 5 phase? Understand newer drives would be 3 phase stepper motors, and would run different voltage, 120-240 V vs 62 V. I can change out transformer in machine for this, would like to know if its possible to put in a more modern drive that will interface the same way old drives make signal connection, assume some cable changes would be needed. Would this be a plug and play type thing?
Install new motors, run new cables to drives, supply drives with proper power, connect drives to signal with new or adapted cables, current cables are 48 pin ribbon, only 15 are used,
I have info that says Berger Lahr MI 3499 drives will work but they seem to be obsolete also. Anyone out there that can help/do. Have put out some RFQs for this, but seems like this could be a R&R job? I have limited electronics knowledge so have to reach out.
Thanks in advance.
