Fault 52 Category 2 explosion protection function
Subfault: 52.1 Description: Startup error | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
One or several parameters of the explosion protection function have been changed. | Before activating the function, start up the explosion protection function. | |
Subfault: 52.2 Description: Invalid function activated | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The explosion protection function and the "standstill current" function may not be active at the same time. | Disable the "standstill current" function. | |
Subfault: 52.3 Description: Nominal inverter current too large | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Ratio of nominal inverter current and nominal motor current too large. | Check assignment of motor and inverter. | |
Subfault: 52.4 Description: Parameterization of current limit characteristic faulty | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Error while setting parameters for current limit characteristic. | – Perform startup again. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Subfault: 52.5 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. | |
