Diagnostics in the CoE
The EL2596 has internal diagnostics. Warnings and errors are also displayed by the LEDs. The diagnostics can be viewed in the CoE objects under 0xA000 “DOX Diag data Ch. 1”.
The warning and error levels for the supply and output voltages can be adjusted in the CoE objects 0x8000:11 – 0x8000:16.
In case of an error, bit 0 “Ready to activate” in the “DOX Status” goes to 0. The LED output can then no longer be set. An error must be rectified and reset via a rising edge on the “Reset” bit in the “DOX Control”. In case of a reset, the “Enable” and “Output” bits under “DOX Control” must be deactivated.
Object | Name | Description | Correction |
|---|---|---|---|
A000:01 | Saturated | Target voltage cannot be reached | Increase Uin or reduce set current |
A000:02 | Over temperature | Warning at internal temperature of 80 °C Error at internal temperature of 100 °C | EL2596 must cool down |
A000:04 | Under voltage (Supply) | Under voltage supply | Increase Uin |
A000:05 | Over voltage (Supply) | Over voltage supply | Reduce Uin |
A000:06 | Short circuit | Short circuit has occurred | Check whether the load is connected correctly and is functional. (not detected during voltage control) |
A000:07 | Open load | Wire breakage detected | Check whether the load is connected correctly and is functional. (not detected during voltage control) |
A000:09 | Misc error | Internal hardware error |
|
A000:0B | Over voltage (Output) | Overvoltage on the digital output | Reduce output voltage |
