Fault list – safety technology
Fault 13 Encoder 1
Manual – Fault Descriptions MOVISAFE® CS..A 13
Subfault: 13.71
Description: Response time of safety card exceeded
Response: FS – warning
Cause Measure
The response time for calculating the speed or
acceleration cannot be adhered to. This can be
due to the following reasons:
– The safety card has received more corrupt tele-
grams from the encoder than the error tolerance
allows.
– The actual refresh time of the encoder is
greater than parameterized.
– Check the wiring.
– Check the encoder.
– Adjust the refresh time to the value in the en-
coder manual.
– If the fault occurs repeatedly, replace the safety
card and send it together with the fault number to

SEW‑EURODRIVE Service.
INFORMATION
In "Emergency mode" manual mode, you can
move the drive using the motor encoder even if
the external position encoder is faulty.
Subfault: 13.72
Description: Internal fault – overflow during position calculation
Response: FS – warning
Cause Measure
Overflow detected during internal calculation of

– Numerator scaling/denominator scaling of the
encoder.
– User units of the position.
Subfault: 13.73
Description: Encoder range overflow pending
Response: FS – warning
Cause Measure
The encoder is just before overflow. The system
is too fast. The position difference is above the
1/4 encoder range. With 1/2 encoder range, an
undetected reversal of the direction of rotation oc-
curs and consequently a permanent error in posi-
tion.
– Reduce the system speed.
– Use an encoder with a larger encoder measur-
ing range (resolution/multi-turn range).
