Note 1: The switch on/off of the dynamic brake can be controlled by P4.30;
Note 2: The electromagnetic brake signal iS set by P3.57; if the speed is less than the setting value of
P3.58 during the time of P3.57, the BRK signal will become valid;
Note 3: The actual Electric level corresponding to input/output valid state Can be set by P3.00~P3.15.
