[ 0 ]
Automatic error acknowledgement should not be used in association with a safety function.
0 = No automatic error acknowledgement.
A full description of the function can be found in Manual BU 0200 GB.

From Firmware V1.3
The frequency inverter is equipped with an internal EEPROM, which is primarily used for the
storage of fault-relevant data and operating hours. If an external EEPROM "Memory Module"
is not plugged in, the parameter settings are also saved in the internal EEPROM. The data
sets saved in the internal EEPROM and in the Memory Module can be copied between the
devices.
0 = No change
1 = External → Internal EEPROM, the
data set is copied from the Memory
Module (external EEPROM) to the
internal EEPROM
2 = Internal → External EEPROM, the
data set is copied from the internal
EEPROM to the Memory Module
(external EEPROM)
3 = Exchange data sets, the data sets are
exchanged between the two
EEPROMs
Note: The frequency inverter always uses the data set which is stored in the external
EEPROM (Memory Module). The parameterisation of the internal EEPROM is only used if no
Memory Module is plugged in.
P559 DC Run-on time S P
0.00 ... 5.00 s
[ 0.50 ]
After a stop signal and elapse of the brake ramp, direct current is applied to the motor for a
short time. This should completely stop the drive. Depending on the inertia, the time for which
the current is applied can be set in this parameter.
The current level depends on the previous braking procedure (current vector control) or the
static boost (linear characteristic).

Present operating status
0.0 ... 21.4 Display of current messages for the actual operating status of the frequency inverter such as
errors, warnings or the cause of a switch-on block. For details of the messages, please refer to
Section 9 and manual BU 0200 GB.
[-01] = Present fault, shows the currently active (unacknowledged) fault (Section 9).
[-02] = Present warning, indicates a current warning message (BU 0200)
[-03] = Reason for disabled starting, indicates the reason for an active start disable (BU 0200)
