 Small current detection
The brake release request signal is not output during f325 (Brake releasing waiting time)
setting time after the brake release (the torque command is issued) after the run command is
ON.
When f326 (Brake releasing small current detection level) is set, the inverter trip as
low-current operation fault (uc) if the output current is f326 or less after a lapse of f325
setting time.
When f326 =0, the small current detection is not active.
In case of using learning function, f325 setting time is not include learning time because the
brake request signal is not output during f325setting time.
When f325 and f345 are set, the inverter check the current for the small current detection
after a lapse of f345 setting time if f325>f345.
