 Overload stop function
Load judgment is performed when the judgment delay time after reaching speed (d186) is passed when hoisting
(FWD), and operation is stopped due to an overload if the overload detection level (d187) is exceeded. It is
recommended that judgment be based on the low speed frequency to ensure that overloads can be detected when
hoisting grounded loads.
Digital output “LLIM” is turned ON at the same time as the overload is detected, and “e-ld” is displayed on the
keypad. If lowering (REV) is possible, and the REV command is turned OFF after the load has been lowered to the
floor, “LLIM” turns OFF, and “e-ld” disappears. In the interests of safety, adjustment of the load detection function
gain and offset (d171 to d174) must be complete to use this function.

 Overload detection “LLIM” assignment (Function code data = 158)
By assigning this signal to a digital output, the inverter is able to monitor that an overload has been detected. The
signal turns ON when an overload is detected, the REV command is turned ON to lower the load, and when lowering
stops (REV = OFF), this signal also turns OFF.
