4.3. Saving Parameter
The parameters of the absolute rotary en-
coder are saved in a non-volatile FLASH
memory. Because of a limited number of writ-
ing cycles ( 1,000), it is useful to transmit the
modified parameter in the first step only in the
RAM area. After adjusting and examination, those values can be saved in the FLASH mem-
ory. After successful saving of the parameter
the encoder sends his MAC-ID on the bus. To
get the process value a new allocation of the
slave is required.
Example:
(MAC-ID Master: 0A hex, MAC-ID Slave: 03
hex)
5. Transmission of the actual position
The process value is transmitted according to
the following table.
