bit.10 - 1 = control of the output RL1;
bit.11 - 1 = control of the output RL2;
bit.12 - 1 = control of the output RL3.
Low-order bits: define the status desired for each output:
bit.0 - output status DO1: 0 = output inactive, 1 = output active;
bit.1 - output status DO2: 0 = output inactive, 1 = output active;
bit.2 - output status RL1: 0 = output inactive, 1 = output active;
bit.3 - output status RL2: 0 = output inactive, 1 = output active;
bit.4 - output status RL3: 0 = output inactive, 1 = output active.
4. Parameter Number to be Read:
Through this position you can read any inverter parameter.
You must enter the number corresponding to the desired parameter and its
content will be displayed in Position 4 of the "Read Inverter Variables".
5. Number of the Parameter to be changed:
(Parameter Content Changing)
This position works jointly with Position 6 below.
If no Parameter change is desired, you have to enter in this position the code
999.
During the changing process you must:
1) Maintain in Position 5. the code 999;
2) Change the code 999 by the parameter number you want to change;
3) If no fault code (24 to 27) is displayed in the E.L., replace the code number by
the code 999, to end the change.
The change can be checked through the HMI or by reading the parameter content.
NOTES!
1) The control change from Scalar Control to Vector Control will not be accepted
if any of the parameters P409 to P413 is set to zero. This must be effected
through the HMI.
2) Do not set P204 = 5, since P309 = Inactive in the factory setting.
3) The desired content must be maintained by the master during 15.0 ms.
Only after this time you can send a new value or write another parameter.
6. Content of the Parameter to be changed, selected at Position 5.
(Number of the Parameter to be changed)
The format of the values set at this position must be as described in the Manual,
but the value must be written without the decimal point, when the case.
When Parameters P409 to P413 are changed, small content differences can
occur, when the value sent via Fieldbus is compared with the value read at Position
4 ("Parameter Content"), or with the value read via HMI. This is due the truncation
(rounding off) during the reading process.
During the read/write process via Fieldbus the following variable indications in
the Logical Status can occur:
Indications in the Logical Status variable:
E24 - Parameter changing only permitted with disabled inverter.
- Parameter setting fault (refer to item 4.2.3).
E25 - Caused by:
- Read Parameter inexistent, or
- Write Parameter inexistent, or
- Write in P408 and P204.
