4-2 Function Mode Overload limit level b022 Deceleration set by the overload limit parameter Output current Maximum frequency A004/A204 Target frequency F001 Inverter output frequency b023 „ Overload Warning 4 •If the load is too large, this function outputs an overload warning signal, allowing you to readjust the overload level to prevent a trip. This helps prevent mechanical damage due to an overload in the conveyors, or an operation line stop due to an overload trip of the Inverter. •Allocate 03 (OL) to the multi-function output (terminal P1, P2) or relay output.
Functions n Overload limit level b022 Overload warning level C041 Output current OL Soft Lock Function Use this function to prohibit writing of each parameter. This helps prevent data rewrite due to erroneous operation. For the soft lock selection through the signal input from the terminal (b31 = 00 or 01), refer to the Soft Lock Function of the Multi-function Input section in "Soft Lock Function" (page 4-47). •This helps prevent data rewriting due to erroneous operation. •Select the soft lock setting and performing method from the above table. •When using the multi-function input, allocate 15 (SFT) to it. 4-30 Parameter No.
