F0041,
Motor data
identification
failure
• Alarm value = 20:
Identified IGBT ON-
voltage less than 0.5 or
more than 10V.
• Alarm value = 30: Current
controller at voltage limit.
• Alarm value = 40:
Inconsistency of identified
data set, at least one
identification failed.
Percentage values based
on impedance
Zb =
Vmot,nom/sqrt(3)/Imot,nom.
0: Check if the motor is
connected to the SED2.
1-40: Check if the motor data in
P0304 to P0311 are correct.
Check the type of motor wiring
required (star, delta).

F0051,
Parameter
EEPROM
fault
Read or write failure while
saving non-volatile
parameter
Reset SED2 to factory setting and
perform quick commissioning.
Off2
F0052,
Power stack
fault
Read failure for power stack
information or invalid data.
Replace SED2. Off2
F0053, I/O
EEPROM
fault
Read failure for I/O
EEPROM information or
invalid data.
• Check the data.
• Replace the I/O module.
Off2
F0054,
Wrong I/O
connection
I/O connection is invalid.
• Check data flow.
• Replace I/O module.
Off2
F0060, ASIC
timeout
Internal communication
error.
• If error reappears, replace SED2.
• Contact your supplier.
Off2
F0070, CB
setpoint fault
No setpoints from CB
(communications board or
module) during telegram off
time.
Check CB (communications board
or module) and communications
partner.
Off2
F0071, USS
(BOP link)
setpoint fault
No setpoints from USS
during telegram off time.
• Check communications to data
transmission module.
• Check USS master.
Off2
F0072, USS
(COM link)
setpoint fault
No setpoints from USS
during telegram off time
Check USS master. Off2
