LinMot Drive Configuration over Fieldbus
The value of any parameter is stored as an integer value (raw data) in
the memory space of the drive. The parameter is identified through its
Unique Parameter ID (UPID), which is a 16 Bit integer number.
Both, UPID and raw data value of any parameter can be displayed in
the LinMot-Talk parameter tree structure (press Show/Hide Details

Figure 2: Detailed view for parameters
The value of any parameter is stored in the non-volatile memory area
of the LinMot drive (ROM value). During the boot-up process the
drive's operating system creates a copy of the non-volatile memory
block to its RAM memory space. Thus, after the drive has powered
up, each parameter has two memory locations and values: one in the
ROM, the other in the RAM.
The firmware uses at run time exclusively the RAM values of the
parameters in its control tasks (fast data access). The drive's
