6.5.17 Fault 20 Device monitoring
Subfault: 20.1
Description: Supply voltage fault
Response: Output stage inhibit
System state: Fault ackn.with CPU reset
Cause Measure
Internal electronics supply voltage or externally connected 24V
standby supply voltage outside 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 fault.
– Replace the device if the fault reoccurs. Contact
SEW‑EURODRIVE Service if you require further support.
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 in the device is too high.
The device signal output of the device was de-energized be-
cause of the fault message.
Identify the consumer that causes the overload at the internal
supply voltage:
1. Remove all external consumers:
– from the digital output terminals of the basic device.
– from other installed options.
– from all encoder connections.
– from all other consumers at the 24V output voltage termin-
als.
2. Acknowledge fault.
3. Connect the consumer to the device again, one after the
other, until the fault message is issued again.
4. To eliminate the fault, use a consumer with a lower current
consumption or eliminate the short circuit.
Subfault: 20.7
Description: Internal hardware fault
Response: Output stage inhibit
Cause Measure
Error detected in device hardware – Acknowledge fault.
– Replace the device if the fault reoccurs. Contact
SEW‑EURODRIVE Service if you require further support.
Subfault: 20.8
Description: Fan warning
Response: Warning with self reset
Cause Measure
Fan function impaired Check fan for proper functioning.
Subfault: 20.9
Description: Fan fault
Response: Application stop + output stage inhibit
Cause Measure
Fan defective Replace the fan.
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.
