Fault 20 Device monitoring
Subfault: 20.1 Description: Supply voltage fault | ||
|---|---|---|
| Response: Output stage inhibit System state: Fault acknowledgment with CPU reset | |
Cause | Measure | |
24 V power supply unit overloaded. | Check the project planning for the power demand. | |
The internal electronics supply voltage or externally connected DC 24 V standby supply voltage is outside the permitted voltage range. | – Check the voltage level of the external DC 24 V standby supply voltage and check for correct connection. If required, correct. – Acknowledge the fault. – If the fault occurs repeatedly, replace the device. For further support, contact SEW‑EURODRIVE Service. | |
Subfault: 20.2 Description: Supply voltage overload | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
For MOVIDRIVE® system, the current load of the current paths of the DC 24 V standby supply voltage inside the device is too high. The device signal outputs of the device were de-energized because of the fault message. | Identify the consumer that is overloading the internal supply voltage: 1. Remove all external consumers: – At the digital outputs of the basic device. – At options that may be present. – At all encoder connections. – At other consumers at the DC 24 V output voltage terminals. 2. Acknowledge the error. 3. Reconnect the consumers with the device, one after the other, until the fault message appears once again. 4. To eliminate the fault, connect a consumer with a lower current consumption or eliminate the short circuit. | |
Subfault: 20.7 Description: Internal hardware fault | ||
|---|---|---|
| Response: Output stage inhibit System state: Fault acknowledgment with CPU reset | |
Cause | Measure | |
Fault in the device hardware. | – Acknowledge the fault. – If the fault occurs repeatedly, replace the device. For further support, contact SEW‑EURODRIVE Service. | |
Subfault: 20.8 Description: Fan – warning | ||
|---|---|---|
| Response: Warning with self-reset | |
Cause | Measure | |
Fan function impaired. | Check the fan for proper functioning. | |
Subfault: 20.9 Description: Fan – fault | ||
|---|---|---|
| Response: Application stop + output stage inhibit | |
Cause | Measure | |
Fan defective. | Contact SEW‑EURODRIVE Service. | |
Subfault: 20.10 Description: Fan – supply voltage fault | ||
|---|---|---|
| Response: Emergency stop + output stage inhibit | |
Cause | Measure | |
Supply voltage of fan missing. | Check the connection or establish a connection. | |
Subfault: 20.11 Description: STO – switching delay | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Switching delay between STO signals F-STO_P1 and F-STO_P2. | – Check the STO wiring. – Before acknowledging the fault, make sure that both STO signals are switched to low level. | |
Subfault: 20.23 Description: Power section temperature detection | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Fault in the device hardware. Power section does not provide temperature data. | – Acknowledge the fault. – If the fault occurs repeatedly, replace the device. For further support, contact SEW‑EURODRIVE Service. | |
Subfault: 20.24 Description: Required communication module missing | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
A communication module used in the device configuration has been removed. | Plug in the module again. | |
Subfault: 20.25 Description: Communication module added | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
A communication module that is not used in the device configuration has been added. | Remove the communication module. | |
