Function:
With these parameters, it is possible to see up to twenty saved values,
or data logs. Data log [1] is 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 drive is stopped, the 20
latest data log entries will be saved and the values will be visible in the
display. This is useful to view the operation of the drive just before a
trip. These values will be lost if power is removed from the drive.
The drawing below shows a display. The data log number is shown in
the square brackets at the left of the forth line of the display.

Data logs [1] through [20] can be read by first pressing CHANGE
DATA, followed by the + and - keys to change data log numbers.
Parameters 606 through 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 is 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 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 is given in decimal code for the control
word of the drive. The control word can only be changed via serial
communication. The control word is read as a decimal number which is
to be converted into hex. See the control word profile under the section
Serial communications.
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. See the status word profile under the section Serial communica-
tion.
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.
