Fault 52 Category 2 explosion protection function
Fault: 52.1 (3401hex | 13313dec) Description: Startup fault | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
One or more parameters of the explosion protection function have been changed. | Before activating the function, take the explosion protection function into operation. | |
Fault: 52.2 (3402hex | 13314dec) Description: Invalid function activated | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The explosion protection function and the "standstill current" function cannot be activated at the same time. | Deactivate the "standstill current" function. | |
Fault: 52.3 (3403hex | 13315dec) Description: Nominal inverter current too large | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Ratio of nominal inverter current and nominal motor current too large. | Check the assignment of motor and inverter. | |
Fault: 52.4 (3404hex | 13316dec) Description: Parameterization of current limit characteristic faulty | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Fault detected in the parameterization of the current limit characteristic. | – Perform startup again. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Fault: 52.5 (3405hex | 13317dec) Description: Time duration exceeded for f < 5 Hz | ||
|---|---|---|
| Response: Emergency stop + output stage inhibit | |
Cause | Measure | |
The rotating field frequency must not be below 5 Hz for longer than 60 s. This time period has been exceeded. | – Check the project planning. – Make sure that work is not performed below 5 Hz for a longer period of time. – Check behavior in idle state. For instance, activate the "FCB 01 output stage inhibit" drive function for position hold control on the device. | |
