Parameter
6.2.5

Multiple rating (LD = Light Duty, SLD = Super Light 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.

Multiple rating setting
The above parameter can be set when Pr. 160 = 0.
If the setting of Pr. 570 is changed the factory defaults and setting ranges of the following pa-
rameters will be changed when you clear the parameters or perform a reset.

Tab. 6-6:
The rated current differs according to the inverter capacity.
For the 01160 or less, SLD/LD value of applied motor capacity is the same.
NOTE
When Pr. 570 = "0" (initial value), Pr. 260 "PWM frequency automatic switchover" becomes
invalid. (Refer to section 6.14.1.)
