14
15 == Overview ==
16
17 The faults and warnings of Wecon VD3E series servo drives are graded according to their severity, which can be divided into four grades: Category 1, Category 2, Category 3, Category 4.
18
19 Severity level: Category 1> Category 2> Category 3 > Category 4. The specific types are as follows:
20
21 Category 2: non-clearable faults;
22
23 Category 2: clearable faults;
24
25 Category 3: clearable faults;
26
27 Category 4: clearable warning.
28
29 Among them, "clearable" means that the panel stops the fault display state by giving a "clear signal". The specific operations are as follows:
30
31 * Set the parameters 200A-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.
32 * 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 2.
33 * The clearing method of category 4 of clearable warnings: set 200A-03=1 or use DI function 2.

38 )))
39 |For some faults and warnings, please 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 the device to be re-powered to take effect, the device must be re-powered; for the changes that need to stop the device to take effect, the servo must be disabled. After the changes take effect, the servo drive is running normally.

73 Wecon VD3E series bus servo drives have a fault recording function, which could record the latest 5 faults and the latest 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.
74
75 The current fault code could be viewed through the monitoring parameter U1-01, and the current warning code could be viewed through U1-02. The monitoring U1-16 to U1-25 could display the latest 5 fault codes and warning codes. Please refer to"201Fh Group: warning monitoring".
