Significance of
fault bits YW2, with
HM2 → YF2
YW2→YF2
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
Bit 2 Overcurrent M1
→
check the system values, connector CAV.CX1 and
initialization connections CAV: RRC, ARC, NF, XFO, AL1
Bit 3 Overcurrent M2
→
check the system values, connector CAV.CX2 and
initialization connections CAV: RRC, ARC, NF, XFO, AL2
Bit 4 CAV configuring error
→
check the initialization connections, CAV:
RRC, ARC, AL1, AL2, IAV, XF2, NF, XFO
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
Bit 6 EMF configuring error
→
check the initialization connections EMF: RRV, ARV, AAV, XFO
Bit 7 Pulse position error (PC6)
Cause: Erroneous pulse position
→
check the line supply values and connectors PC6: DIL, DIZ
Bit 8 Configuring error
→ AAV voltage specified too high (1.35*AAV > 2*ARU)
Fault, zero current signal for M1 ⇔ M2
Bit 9
→
check the zero current signal from the SITOR interface
(only with NZM=0)
Bit 10 SOL configuring error
→
check the initialization connections SOL: TH0, TCP
Bit 11 SOL block, internal status fault
→
check the ITDC hardware
Bit 12 FCS configuring error
→
check the initialization connections FCS: RRC, ARC and FC
Bit 13 PA6 configuring error
→
check the initialization connections PA6: NAZ, NEP, NWD, INV, FNT
Bit 14
configuring error
PC6
→ check the initialization connections
