3.2 Parameter operation
The unit specific parameters can be read and changed in Parameter Operation.
Before writing parameters a write enable must be sent. Then it is possible to change a single or
several parameters. On closing the write enable must be removed. A read request only is required for
reading
The response value of Word 3 is always “C0DE“ H. This is used by the controller to indicate that it is
running in parameter mode.
3.2.1 Parameter address and value formatting
In parameter operation the most significant bit in Word 1 defines the “read/write” (R/W) bit (1 = Write,
0 = Read) and must be given with parameter address of the corresponding parameter.
Normal or parameter operation are selected by using the mode bit (most significant bit in word 3 (0 =
Normal-, 1 = Parameter operation).
Word 1:
R / W
–
Bit + Address
e.g. 8000 H + 1009 H => 9009 H
Word 2:
Parameter value.
e.g. 7FFF H
Wort 3:
Mode bit = 1 + control b
its
e.g. 8000 H + 0004 H => 9004 H
For bit configured parameters only those bits that correspond to the required characteristic may
be altered. All other bits must not be changed; otherwise the basic settings for the load could be
altered.
The procedure for adjustment using bit parameters is as follows:-
1. Read parameter value.
2. Only alter the required bit value(s) for the parameter which is chosen.
3. Switch on the write enable.
4. Write the changed parameter value back to the same address.
5. Remove the write enable.
