controller variant • Consult SEW Service
• Replace precharge/dis-
charge control
3 Inverter coupling Defective inverter coupling • Consult SEW Service
• Replace inverter coupling
4 Inverter coupling reference
voltage Defective inverter coupling • Consult SEW Service
• Replace inverter coupling
5 Power sections configura-
tion Different phase modules in-
stalled in the unit • Inform the SEW Service
• Check and replace phase
modules
6 Control unit configuration Control unit line inverter or mo-
tor inverter incorrect Replace or correctly assign
the control unit of line and mo-
tor inverter
7 Communication power
section control unit No communication Check control unit installation
8 Communication pre-
charge/discharge control
inverter coupling No communication • Check the cabling.
• Consult SEW Service
10 Communication power
section control unit The inverter coupling does not
support protocol Replace inverter coupling
11 Communication power
section control unit Faulty communication with in-
verter coupling at power-up
(CRC fault) Replace inverter coupling
12 Communication power
section control unit Inverter coupling uses protocol
that does not match control unit Replace inverter coupling

tion Immediate
stop 14 Control unit configuration Missing PLD functionality for
EEPROM data set size 7 Replace control unit
15 Inverter coupling fault Inverter coupling processor has
signaled internal fault • Consult SEW Service if the
fault occurs again.
• Replace inverter coupling
16 Inverter coupling fault:
PLD version incompatible Replace inverter coupling
17 Precharge/discharge con-
trol fault Precharge/discharge control
processor has signaled internal
fault • Consult SEW Service if the
fault occurs again.
• Replace precharge/dis-
charge controller
18 Defective DC link fan Faulty DC link fan • Consult SEW Service
• Check whether DC link
choke fan is connected or
faulty
