Subfault: 19.9
Description: Jerk setpoint violation
Response: Application stop + output stage inhibit
Cause
Measure
Jerk values not plausible.
Adjust jerk setpoints.
8.6.16
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 con-
nection. 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 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 fault.
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.
