Overload Warning - Omron 3G3JX User Manual

• 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.

•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.
