The driver is now broken, and unrepairable. Would you know if I can use any other Yaskawa drive with this motor?
I understood if the voltage 200V and the power 300w are the same, it should work?
The encoder has 3 parallel channels, unlike the modern serial encoders. This should be matched also as I understood.
I have been searching for second hand Yaskawa drives , and for me it seems that Yaskawa sigma DR2 drive could work
Does anyone have any experience with this kind of replacements?
The system is controlled with num750 controller, analog +-10v, encoder feedback.
Thank you very much for any further information,
Joe
