Subfault: 16.25
Description: User-defined current limit too low for standstill current
Response: Output stage inhibit
Cause Measure
User-defined current limit value too small for minimum standstill
current.
Increase the user-defined current limit, or disable the standstill
current function.
Subfault: 16.26
Description: Nominal values incomplete or implausible
Response: Output stage inhibit
Cause Measure
During startup using nameplate data: Nominal voltage, nominal
current, nominal speed or nominal torque are not entered or
are not plausible.
Enter or check nominal voltage, nominal current, nominal
speed, and nominal torque.
Subfault: 16.27
Description: Maximum current or maximum torque not plausible
Response: Output stage inhibit
Cause Measure
During startup using nameplate data: Maximum current or max-
imum torque not entered, or maximum current and maximum
torque not plausible.
Check the maximum current and maximum torque.
Subfault: 16.30

10.5.14 Fault 17 Internal processor fault
Subfault: 17.7
Description: Exception error
Response: Output stage inhibit
Cause Measure
Exception trap in CPU. Contact SEW-EURODRIVE Service.
10.5.15 Fault 18 Software error
Subfault: 18.1
Description: Motor management
Response: Output stage inhibit
System state: Fault acknowledgment with CPU reset
Cause Measure
Error detected at motor management interface. – Switch the device off and on again.
– Contact SEW‑EURODRIVE Service if the fault persists.
Subfault: 18.3
Description: Task system warning
Response: Warning
Cause Measure
Error while processing internal task system. This may be a
timeout for cyclical tasks, for example.
– Acknowledge the warning.
– Contact SEW‑EURODRIVE Service if the warning occurs
regularly.
Subfault: 18.4
Description: Task system
Response: Output stage inhibit
System state: Fault acknowledgment with CPU reset
Cause Measure
A fault was detected during the processing of the internal task
system. This may be a timeout for cyclical tasks, for example.
– Switch the device off and on again.
– Contact SEW‑EURODRIVE Service if the fault persists.
