EMC STANDARDS
Mitsubishi Electric general-purpose AC servo MELSERVO complies with the product family standard EN 61800-3. This
standard largely regulates two types of tolerance, emission and immunity.
Emission (EMI: Electromagnetic Interference) is the ability to prevent equipment from emitting obstructive noise that
adversely affects external sources.
Immunity (EMS: Electromagnetic Susceptibility) is the ability to prevent equipment from being affected by obstructive noise
from external sources.
The following table shows the classification.
*1 The latest standards applicable to servo systems. For the standards of the servo motor to be used, refer to the instruction manual and
user's manual of the servo amplifier to be used.
