EEPROM data
Cause in the parameterization:
The control card was replaced and, after initialization,
detects a new power section, which for example,
cannot supply the parameterized currents. This means,
that one or several parameters lie outside the tolerance
range. When the fault is acknowledged, the associated
parameters are reset to the standard drive converter
values.
Cause in the drive converter:
This fault can also occur if the power fails during
operation. In this case, the power section could send
incorrect data to the control card.
Alarm / fault
The appropriate parameter numbers can be viewed
using P0061.XX, and the erroneous parameter values
using P0062.XX.
The fault can be removed using a special
acknowledgement with P0060 (password level 3 [Esc],
[Mon], [Prog] and [+]). It must then be checked,
whether the modified parameters match the particular
application.
When parameterization is exited, the values are
transferred into the Eeprom.
The fault may be able to be removed by powering-up
and powering-down the line supply voltage or the
standby supply. If this is not successful, then please
call customer service.
21
Internal WS comm.
Communications between the processor board and the
power section are faulted. If the fault occurs after
power-up during the self-test, it cannot be
acknowledged.
Fault
Check the plug connection between the PC boards or
replace the modules.
22
NTC power section
Wire broken/interrupted to the NTC on the heatsink in
the power section or rectifier; NTC defective; excessive
resistance (high ohmic connection) or the connector
does not have a contact.
Fault
Check the plug connector; replace the connector, cable
or NTC.
24
SS1 timeout
The control computer does not send data within the
parameterized response time (P0506).
Alarm / fault
Check the plug connection SS1 (RS485), extend the
response time (P0506), select another response type
(P0505).
SS2 function
Only for option interface cards at option slot 1.
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 P0509; this means that
the system can continue to operate!
25
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
P0509; this means that the system can continue to
operate.
Only for the Profibus option: Either “No action” or
“Fault” can be selected in parameter P0524 when
receiving Clear Data.
Caution: In this case, P0509 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.
26
SS2 timeout
Only for option interface cards at option slot 1.
Within the parameterized response time (P0527), the
higher-level control computer does not send any data.
Alarm / fault
Check plug connection SS2
Extend the response time (P0527), select another
response type (P0526).
