Hi,
I'm working on Mitsubishi MR-J5-70A amplifier, and need some advice on selecting fuse size.
Main power is 1ph 240VAC, and in the manual, it says that for main power, 1ph 240VAC for rated current of 6.5A and for controller power, 1ph 250VAC with rated current of 0.2A.
Is it ok to use 6.5A fuse for main power and 0.2A fuse for controller power?
or is there any calculation related to selecting proper fuses?

Thanks,
 
With drives or servo amps, I normally find circuit protection recommendations in the manual and follow those as closely as possible. Often, the rated power usage doesn't account for inrush current and if you use the breaker or fuses recommended by the manufacturer, you have something in writing to point at in case something does fail or trip and your decision receives scrutiny.
