YW2→YF2 Fault message → remedy Source
Bit 1
Hardware fault of the current actual value sensing (Sitor)
ITDC: Current actual value has not been latched (saved).
Cause: V/f conversion frequency not present
→ check the current actual value sensing (60 kHz) or ITDC
CAV
Bit 2
Overcurrent M1
→ check the system values, connector CAV.CX1 and
initialization connections CAV: RRC, ARC, NF, XFO, AL1
CAV
Bit 3 Overcurrent M2
→ check the system values, connector CAV.CX2 and
initialization connections CAV: RRC, ARC, NF, XFO, AL2
CAV
Bit 4 CAV configuring error
→ check the initialization connections, CAV:
RRC, ARC, AL1, AL2, IAV, XF2, NF, XFO
CAV
Bit 5
Hardware fault: Voltage actual value sensing (Sitor)
ITDC: Voltage actual value has not been latched (saved).
Cause: V/f conversion frequency not present
→ check the voltage actual value sensing (60kHz) or ITDC
EMF
Bit 6 EMF configuring error
→ check the initialization connections EMF: RRV, ARV, AAV, XFO
EMF
Bit 7 Pulse position error (PC6)
Cause: Erroneous pulse position
→ check the line supply values and connectors PC6: DIL, DIZ
PC6
Bit 8 Configuring error
→ AAV voltage specified too high (1.35*AAV > 2*ARU)
Bit 9
Fault, zero current signal for M1
⇔ M2 (NZM=0, Sitor) or Iact >3%
→ check the zero current signal from the SITOR interface
(only with NZM=0)
SOL
Bit 10
SOL configuring error
→ check the initialization connections SOL: TH0, TCP
SOL
Bit 11 SOL block, internal status fault
→ check the ITDC hardware
SOL
Bit 12 FCS configuring error
→ check the initialization connections FCS: RRC, ARC and FC
FCS
Bit 13 PA6 configuring error
→ check the initialization connections PA6: NAZ, NEP, NWD, INV, FNT
PA6
Bit 14
PC6
configuring error
→
check the initialization connections PC6: LDU, LDL, AWS, DAG, DAW
PC6
Bit15-16
Logical 0
