I have a KIA KIT 30A cnc lathe with equipped spindle drive(inverter) Fuji Frenic 5000 M2(7.5kw Fuji ac induction motor 50-200hz,200V,3ph). I changed the Fuji Frenic 5000M2 because, drive is broken. I fitted Lenze SMD 800 drive.
I am running Lenze drive with 5k pot. very well. But, when i connect to cnc analog 0-10v(SVC) reference voltage, motor is vibrating and 0-10v reference voltage is changing and decreasing.
Can you help me?
Best Regards.
