148 148  The faults and warnings of Wecon VD2 series servo drives are graded according to their severity, which can be divided into four grades: Category 1, Category 2, Category 3, Category 4. Severity level: Category 1> Category 2> Category 3 > Category 4, the specific classifications are as follows:

151 +* Category 2: faults are clearable;

154 -Category 3: faults are clearable;

156 -Category 4: warnings are clearable.

158 158  Among them, "clearable" means that the panel stops the fault display state by giving a "clear signal". The specific operations are as follows:
159 159  
160 160  1. Set the function code P10-03=1 (fault clearing) or use DI function 02 (02-A-CLR, fault and warning clearing) and set it to logic valid, which can stop the fault display on the panel.
