This parameter can detect whether the PID feedback line is missing.
When the PID feedback amount is less than the feedback loss detection value 10-26, and the duration exceeds
the PID feedback loss detection time 10-27, the inverter alarms the fault PIDE, and handles it according to the
selected fault handling method.

It is used to select whether PID continues to operate under PID stop status. In general applications, PID should
stop calculation in the stop state.

0: No protection, no motor overload protection feature (use with caution), at this time, the inverter has no overload
protection for the load motor.
1: At this time, the inverter judges whether the motor is overloaded according to the inverse time limit curve of the
motor overload protection. The inverse time limit curve of motor overload protection is: 220%×(11-01)×motor
rated current, which will alarm the motor overload fault for 1 minute; 150%×(11-01)×motor rated current, which
lasts 60 minutes Then alarm motor overload.
The user sets the value of 11-01 according to the actual overload capacity of the motor. If the setting is too large,
the motor may be damaged due to overheating and the inverter may not alarm in time!

This function is used to output an early warning signal to the control system through the multi-function output
terminal before the motor overload protection. The early warning function can set how much early warning is
given before the motor overload protection. The larger the value,the smaller the early warning advance.
