This is the net value at the rated load. When actually selecting fuses, determine the capacity using the
prescribed derating.
**
Operating characteristics (at 25°C): 2 seconds or more for 200%, 0.01 second or more for 700%
Note: A fast-operating fuse cannot be used because the Servo Amplifier power supply is a capacitor input
type. A fast-operating fuse may blow when the power is turned ON.
