Set 3: Overload Advanced Notice Signal (OL)
Before the VFD becomes overload, N700E generates an advanced warning signal to prevent any
damage by the excessive output current. Overload detection circuit is designed to operate during
powered motor operation and regenerative braking operation. The OL signal becomes ACTIVE
High when the output current exceeds the setpoint programmed in C21, Overload Advance Notice

Set 4: Output Deviation Excess for PID Control (OD)
The PID loop error is defined as the magnitude of the difference between the set point and process
variable. When the error magnitude exceeds the value of C24, the OD terminal signal turns on
