4-2 Function Mode • With the overload limit parameter set too low, an overvoltage trip may occur due to regenerative energy from the motor. This is because of automatic deceleration from this function even during acceleration. • Make the following adjustments if this function operates during acceleration and the frequency doesn't reach the target level. •Increase the acceleration time. •Increase the torque boost. •Increase the overload limit level. •Use a higher rank Inverter. Overload limit level b022 Deceleration set by the overload limit parameter 4 Output current Max.
frequency A004/A204 Target frequency F001 Functions Inverter output frequency b023 •You can change the level setting in the overload limit source selection. With 00 selected, the set values of b022 and b222 are applied to the overload limit level. With 01 selected, the analog voltage input between FV and FC is enabled, and 10 V here corresponds to 150% of the rated current. Note that 01 can be set only if PID is disabled and the AT terminal is not set. „ Overload Warning •If the load is too large, this function outputs an overload warning signal, allowing you to readjust the overload level.
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 any of multi-function output terminal P1 or relay output terminals. n Overload limit level b022 Overload warning level C041 Output current OL 4-32
