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, 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:
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:
This is where the latest log data are given in
decimal code for the control word of the 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.
Parameter 608 Data log: Status 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.
Parameter 609 Data log: Reference:
This gives the latest log data for the resulting reference.
Parameter 610 Data log: Feedback:
This gives the latest log data for the feedback signal.
Parameter 611 Data log: Output frequency:
This gives the latest log data for the output frequency.
Parameter 612 Data log: Output voltage:
This gives the latest log data for the output voltage.
Parameter 613 Data log: Output current:
This gives the latest log data for the output current.
Parameter 614 Data log: DC-link voltage:
This gives the latest log data for the intermediate
circuit voltage.
