147
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:
149
150 * Category 1: faults cannot be cleared;
151 * Category 2: faults are clearable;
152 * Category 3: faults are clearable;
153 * Category 4: warnings are clearable.
154
155 Among them, "clearable" means that the panel stops the fault display state by giving a "clear signal". The specific operations are as follows:
156
157 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.
158 1. The clearing method of category 2 and category 3 clearable faults: first turn off the servo enable signal (set S-ON to OFF), then set P10-03=1 or use DI function 02.
159 1. The clearing method of category 4 of clearable warnings: set P10-03=1 or use DI function 02.

165 |For some faults and warnings, you must change the settings to eliminate the causes before they can be cleared, but clearing does not mean that the changes take effect. For the changes that need to be re-powered to take effect, the power must be re-powered. For the changes that need to be stopped to take effect, the servo enable must be turned off. After the change takes effect, the servo drive can operate normally.

195 VD2 series servo drives have a fault recording function, which could record the last 5 faults and the last 5 warning names and the status parameters of servo drive when the fault or warning occurs. After the fault or warning is cleared, the fault record will still save the fault and warning.

197 The current fault code could be viewed through the monitoring parameter U1-01, and the current warning code could be viewed through U1-02.
