Subfault: 19.9
Description: Jerk setpoint violation
Response: Application stop + output stage inhibit
Cause Measure
Jerk values not plausible. Adjust jerk setpoints.
8.8.16 Fault 20 Device monitoring
Subfault: 20.1
Description: Supply voltage fault
Response: Output stage inhibit
System state: Fault acknowledgment with CPU reset
Cause Measure
Internal electronics supply voltage or externally
connected DC 24 V standby supply voltage out-
side permitted voltage range. Check the voltage level of the external DC 24 V
standby supply voltage and check for correct port.
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 output of the device was de-energized be-
cause of the fault message.
Identify the consumer that is overloading the in-
ternal supply voltage:
1. Remove all external consumers:
– At the digital outputs of the basic unit.
– At options that may be present.
– At all encoder connections.
– At other consumers at the DC 24 V output
voltage terminals.
2. Acknowledge the fault.
3. Reconnect the consumers to the device one
after the other until the fault message appears
again.
4. To eliminate the fault, connect a consumer with
a lower current consumption or eliminate the
short circuit.
