Function:
With these parameters, it is possible to see up to 20
saved values (data logs) - [1] being the most recent
and [20] the oldest log. When a start command has
been given, a new entry to the data log is made every
160 ms. If there is a trip or if the motor has stopped,
the 20 latest data log entries will be saved and the
values will be visible in the display. This is useful, e.g.
in the case of service after a trip.
The data log number is given in square brackets; [1]

Data logs [1]-[20] can be read by first pressing
[CHANGE DATA], followed by the [+/-] keys to change
data log numbers.
Parameters 606-614 Data log can also be read out via
the serial communication port.
Description of choice:
Parameter 606 Data log: Digital input
input::
This is where the latest log data are shown in decimal
code, representing the status of the digital inputs.
Translated into binary code, terminal 16 corresponds
to the bit to the extreme left and to decimal code 128.
Terminal 33 corresponds to the bit to the extreme
right and to decimal code 1.
The table can be used, e.g., for converting a decimal
number into a binary code. For example, digital 40
corresponds to binary 00101000. The nearest smaller
decimal number is 32, corresponding to a signal on
terminal 18. 40-32 = 8, corresponds to the signal on
terminal 27.

Parameter 607 Data log: Control word
word::
This is where the latest log data are given in decimal
code for the control word of the VLT frequency
converter.
The control word read can only be changed via serial
communication.
The control work is read as a decimal number which
is to be converted into hex.
See the control word profile under the section Serial
communication in the Design Guide.
Parameter 608 Data log: Status word
word::
This gives the latest log data in decimal code for the
status word.
The status word is read as a decimal number which is
to be converted into hex.
See the status word profile under the section Serial
communication in the Design Guide..
Parameter 609 Data log: Reference
Reference::
This gives the latest log data for the resulting
reference.
Parameter 610 Data log: Feedback
Feedback::
This gives the latest log data for the feedback signal.
Parameter 611 Data log: Output frequency
frequency::
This gives the latest log data for the output frequency.
Parameter 612 Data log: Output voltage
voltage::
This gives the latest log data for the output voltage.
Parameter 613 Data log: Output current
current::
This gives the latest log data for the output current.
Parameter 614 Data log: DC-link voltage
voltage::
This gives the latest log data for the intermediate
circuit voltage.
