40
Switched-mode power supply
The switched-mode power supply for the electronics
supply does not output a checkback signal.
Fault
Replace the defective switched-mode power supply.
Depending on the drive converter version, the
switched-mode power section is on the PC board:
LT
(power section),
WS
(inverter control) or
SV
(power supply).
41
SR <==> WS new
If the control card is replaced in another drive converter
with a higher or lower output or drive converter index,
this entry is made in the fault memory (the drive
converter does not go into a fault condition!).
A fault is issued if the parameters lie outside the limit
values (refer to fault 19).
44
SS4 function
Only for option interface cards at option slot 2.
The drive converter detects a physical fault on the
interface cable from the higher-level control computer.
Erroneous data transfer along the fieldbus.
Alarm / fault
Check that the PPO type (protocol type), baud rate,
parity, stop bit and slave address are correct.
If a bus error occurs in the form of an alarm or fault,
then the alarm or the fault or both messages can be
suppressed using parameter
P0745, this means that the system can continue to
operate!
Only for the CAN bus option: The protocols sent on the
CAN bus interface are monitored. If a bus error occurs
more than 127x, an alarm is output. If a bus error
occurs more than 255x, a fault is signaled. The alarm
or fault or both messages can be masked in parameter
P0745; this means that the system can continue to
operate.
Only for the Profibus option: Either “No action” or
“Fault” when receiving Clear Data can be selected in
parameter P0524.
Caution: In this case, P0745 should be set to the “All
active” function! This means that the control computer
sends Clear Data if there is an invalid protocol or a bus
error.
Only for the Interbus S option: The response type can
be set in parameter P0518 and the monitoring time,
when a bus error occurs, in P0519.
Index 0 = process data, index 1 = PKW range.
45
SS4 timeout
Error of the internal interface between drive converter
and sinusoidal filter.
Alarm / fault
Verify the parameter P1274, 1275 and 1276 for factory
setting.
47
Start inhibit active
Only for the start inhibit option: The start inhibit was
activated, while the drive converter was not
operational.
Alarm
59
SS6 timeout
Within the parameterized response time (P1275) the
higher-level control computer does not send any data.
Alarm / fault
Check plug connector X13
Extend the response time (P1275), select another
response type (P1276).
61
FUS power supply
The power supply on the KB21004 coupling module is
not operating correctly
Fault
Replace module KB21004
62
Resonance
Current resonance (oscillations) occur at an operating
point between the motor and output filter of the drive
converter.
Fault
Set the operating point differently in the V/Hz
characteristic,
or: Cancel the filter P1224.xx = 0
Disable the output filter for the appropriate parameter
set (P1224.XX)
