Function:
[Index 000.00 - 019.06]
Logging of data for the last few seconds of operation,
before stop or trip.
Description of choice:
Digital inputs
are stated in hex code
(0-FF).
Control words
are stated as a hex code
(0-FFFF) for bus operation RS 485.
Status words
are stated as a hex code
(0-FFFF) for bus operation RS 485.
Reference
is the control signal in percent (0-100%).
Frequency out
is the output frequency of the unit in
Hz (0.0 - 999.9).
Phase current
is an output current in A (0.0 - 999.9).
Direct voltage
indicates the voltage of the
intermediate circuit in [V DC] (0-999).
20 log values are stated (0-19).
The lowest number (0) contains the most recent/last
data value saved; the highest log number (19)
contains the oldest data value.
Data values log every 160 msec. as long as the start
signal is active.
The data log contains the 20 last log values (approx.
3.2 sec.) before a stop signal is given (start not
active), or a trip occurs.
It is possible to scroll through the log values. The data
log is reset during start up (when the mains supply is
restored).
★
= factory setting. Text in ( ) = display text. Figures in [ ] are used when communicating with the bus.

Service and diagnostics, group 6..
In group 6.., different operating data can be recorded
that may be used in connection with service and
diagnostics. Also, this group contains information
about the identity of the unit and the software
version used.

Display of the most important operation data.
Description of choice:
Display range:
Total number of operating hours/Running hours/kWh
is 0.0 - 99999 (below 10000, with 1 decimal).
Number of cut-ins/Number of overheatings/Number
of overvoltages is 0 - 99999.
Serial communication:
Total number of operating hours/Running hours/kWh
is registered in the form of floating decimal point
values.
No. of cut-ins/Number Overheatings/Number
Overvoltages, registered as whole numbers.
Total number of operating hours/Running hours/kWh is
automatically reset after manual initialisation.

The data stated are saved every 8 hours. kWh
can be reset via parameter 011.
Running hours can be reset via parameter 012.
Number of cut-ins/Number of overheatings/Number
of overvoltages are saved as they occur.
