Operating Instructions, 07/2012, A5E03728167
Fault
Cause
Remedy
•
r0949 = 3: The MMC / SD card
cannot read the file
•
r0949 = 4: Reading data from the
clone file failed (e.g., reading failed,
data or checksum wrong)
recreate file if possible.
•
r0949 = 4: File has been changed - recreate file.
F62
Parameter cloning
contents invalid
File exists but the contents are not valid
control word corruption.
Recopy and ensure operation completes.
F63
Parameter cloning
contents incompatible
File exists but was not the correct
inverter type.
Ensure clone from compatible inverter type.
F64
Inverter attempted to do
an automatic clone during
startup
No Clone00.bin file in the correct
directory /USER/SINAMICS/DATA.
If an automatic clone is required:
- Insert the MMC / SD card with correct file and
power cycle.
If no automatic clone is required:
- Remove the card if not needed and power cycle.
- Reset P8458 = 0 and power cycle.
Note:
Fault can only be cleared by a power cycle.
F71
USS setpoint fault
No setpoint values from USS during
telegram off time
Check USS master
F72
USS / MODBUS setpoint
fault
No setpoint values from USS /
MODBUS during telegram off time
Check USS / MODBUS master
F80
AI lost input signal
•
Broken wire
•
Signal out of limits
F85
External fault
External fault triggered via command
input via control word 2, bit 13.
•
Check P2106.
•
Disable control word 2 bit 13 as command
source.
•
Disable terminal input for fault trigger.
F100
Watchdog reset
Software Error
Contact service department or change inverter.
F101
Stack overflow
Software error or processor failure.
Contact service department or change inverter.
F221
PID feedback below
minimum value
PID feedback below minimum value
P2268.
•
Change value of P2268.
•
Adjust feedback gain.
F222
PID feedback above
maximum value
PID feedback above maximum value
P2267.
•
Change value of P2267.
•
Adjust feedback gain.
F350
Configuration vector for
the inverter failed
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.
Internal failures cannot be fixed.
r0949 = 13 - Make sure the right power module is
fitted.
Note:
Fault needs power cycle to be acknowledged.
