Multiple Rating (Sld = Super Light Duty, Ld = Light Duty, Nd = Normal Duty, Hd = Heavy Duty) (Pr. 570) - Mitsubishi Electric FR-A700 Instruction Manual

Adjust the output torque of the motor (current)
6.7.5 Multiple rating (SLD = Super Light Duty, LD = Light Duty, ND = Normal
Duty, HD = Heavy Duty) (Pr. 570)
You can use the inverter by changing the overload current rating specifications according to load
applications. Note that the control rating of each function changes.
