the terminal open.
Sizes G and H: Contacts X80.170 and 171 were
opened during operation, or an on command was
issued with the terminals open-circuit.

Switched power supply
Fault
The switched-mode power supply for the electronic
supply does not output a checkback signal.
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
SI4 function
Alarm / Fault
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
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" and
"fault" when receiving clear data can be selected in
parameter P0524.
Caution: In this case, P0745 should be set to the "all
active" function!
i.e. Clear Data is sent from the control computer, if
there is an invalid protocol or a bus error.
Only for 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
SI4 timeout
Alarm / Fault
Only for option interface cards at option slot 2.
•
Within the parameterized response time, the
higher-level control computer does not send any
data.
•
Check plug connection SS4
•
Extend response time (P0747), select another
response type (P0746).
47
Start protection On (active)
Alarm
Only for the start inhibit option: Start inhibit was
activated, while the drive converter was not in the
operational status.
