BONFIGLIOLI Active Cube User Manual

The values are entered automatically in the EEPROM of the controller. However, only
a limited number of write cycles is permissible for the EEPROM (approx. 1 million
cycles). When this number is exceeded, the EEPROM will be destroyed.
 Values which are written cyclically at a high repetition rate should be written to
the RAM and not the EEPROM.
In the RAM, the data is not protected against loss of power. Once power supply is
disrupted, the data must be written again.
NOTE
8.2.1 Example: Writing of index parameters
Typically, index parameters are written regularly during commissioning or in simple
positioning applications.
Writing of Parameter Target position/distance 1202 (Type double word), in Index 1
in RAM ( Index 34 for write access) with parameter value 30000.
Index = 1200 + 0x2000 = 0x24B0, Wert (int) = 34 = 0x0022
Index = 1202 + 0x2000 = 0x24B2, Wert (long) = 30000 = 0x0000 7530
If various parameters of an index are to be edited, it will be sufficient to set index
access via parameter 1200 once at the beginning.
8.2.2 Example: Reading of index parameters
In order to read an index parameter, you will have to set the indexing parameter to
the relevant index first, then you can read the parameter.
Reading of Parameter Target position/distance 1202 (type long), in Index 1 with
parameter value 123000.
Index = 1201 + 0x2000 = 0x24B1, Wert (int) = 1 = 0x0001
Index = 1202 + 0x2000 = 0x24B2, Wert (long) = 123000 = 0x0001 E078
If various parameters of an index are to be read, it will be sufficient to set index
access via 1201 once at the beginning.
