Hybrid Nema 42 - lookin for a driver

Hello all,

I have a machine that has 3 of these stepper motors but they are old. They are using RTA drivers which I dont know how old they are but we have found no spare cards for them. I want to replace them and keep using the motor which is a hybrid nema 8.9 AMP one but looking for a driver I notice that they dont go over the 7amp peak. Anyone has a recommendation?

Thanks in advance
