Status word bits
See Chapter 12 “APPENDIX 2 – CONTROL AND STATUS
WORD” for status word bit descriptions.
The use of process data depends on the application. In a
typical situation, the device is started and stopped with
the Control Word (CW) written by the Master and the
Rotating speed is set with Reference (REF). With PD1…
PD8 the device can be given other reference values (e.g.
Torque reference).
With the Status Word (SW) read by the Master, the status
of the device can be seen. Actual Value (ACT) and PD1…
PD8 show the other actual values.
7.1.3.5.4. ID map
Using the ID map, you can read consecutive memory
blocks that contain parameters whose IDs are not in a
consecutive order. The address range 10501 – 10530 is
called ‘IDMap’, and it includes an address map in which
you can write your parameter IDs in any order. The address
range 10601 -10630 is called ‘IDMap Read/Write,’ and it
includes values for parameters written in the IDMap. As
soon as one ID number has been written in the map cell
10501, the corresponding parameter value can be read
and written in the address 10601, and so on. The address
range 10701 – 10730 contains the ID Map for 32bit values.
Maximum of 30 IDs and ID values can be written and read
with single request except in Eaton MMX it is possible to
access only 12 ID value items at a time.
otee: N 32 bit data not supported in the current version. See
chapter 5.

ID Map
Once the ID Map address range has been initialized with
the parameter IDs, the parameter values can be read and
written in the IDMap Read/Write address range address
(IDMap a 100).

Address Data
10601 Data included in parameter ID700
10602 Data included in parameter ID702
10603 Data included in parameter ID707
10604 Data included in parameter ID704
If the ID Map table has not been initialized, all the fields
show index as ‘0’. If it has been initialized, the parameter
IDs included in it are stored in the flash memory of the
OPTE9 option board.

7.1.3.5.5. Operation day counter
Control unit operating time counter (total value). This
counter cannot be reset. The values are read only.
Operation day counter as seconds
This counter in registers 40011d to 40012d holds the value
of operation days as seconds in a 32-bit unsigned integer.
