SINAMICS V20 Inverter
Operating Instructions, 11/2016, A5E34559884-006
Cause
Script of the internal inverter program
has stopped running due to script errors
except for forced exit.
PID feedback below minimum value
P2268.
PID feedback above maximum value
P2267.
During startup the inverter checks if the
configuration vector (SZL vector) has
been programmed correctly and if
hardware matches the programmed
vector. If not the inverter will trip.
r0949 = 1: Internal failure - no hard-
•
ware configuration vector available.
r0949 = 2: Internal failure - no soft-
•
ware configuration vector available.
r0949 = 11: Internal failure - inverter
•
code not supported.
r0949 = 12: Internal failure - soft-
•
ware vector not possible.
r0949 = 13: Wrong power module
•
fitted.
r0949 > 1000: Internal failure -
•
wrong I/O board fitted.
This fault occurs after a startup clone. It
can also be caused by a faulty read
from the EEPROM, see F51 for more
details.
A startup clone could have changed
and might not match the application.
This parameter set needs to be
checked before the inverter can start a
motor.
r0949 = 3/4: Inverter data change
•
r0949 = 5: Startup clone via an SD
•
card has been performed
r0949 = 10: Previous startup clone
•
was aborted
Remedy
Check the script and make necessary corrections.
Change value of P2268.
•
Adjust feedback gain.
•
Change value of P2267.
•
Adjust feedback gain.
•
Internal failures cannot be fixed.
r0949 = 13 - Make sure the right power module is
fitted.
Note:
Fault needs power-cycle to be acknowledged.
The current parameter set needs to be checked and
confirmed by clearing the fault.
