This function is to protect motor overheating when motor does not use thermal relay.
Inverter using some parameters to calculate motor temperature rise, at the same time to determine
whether the use of current caused motor overheat. When you choose electronic thermal protection
function, the drive output is shutdown after overheating detected also shows information of
protection.

A24 set the electronic thermal protection level. When the current is the rated motor current
multiples the parameter, the drive in 1 minute protects, thermal protection within one minute that
means the actual current is A24 times of the rated current

A25 Fault reset times
In the inverter operation process, Over Current expressed by OC、Over Voltage by OU,
inverter can automatically recover and run with state of preceding fault. Recovering times will be
according to this parameter. It can set 10 times at most. When this parameter is set "0", inverter
will not automatically recover after meeting fault. But if relay in DC main circuit meet fault
"MCC" or less voltage "LU" fault, inverter will automatically recover without limitation.
Restarting from fault and normally running over 36s, inverter will automatically recover
fault reset times preset.
Restarting from fault and normally running over 36s, inverter will automatically recover to
display monitor parameter.
