General

The "Flexible memory configuration" function allows the user to influence the memory page
allocation for:
• User data
– Part program data
– UMS data
– IKA data
– R parameters
– TO data
– Data for real axes
– Data for extended overstore
• Drive software
In the case of analog drive systems, the memory space reserved for digital drive software
can be used to store user data.
• Number of axis-specific measured values:
For the "Extended measurement" function.
• Number of block buffers in block memory:
Depending on the capacity utilization of individual channels, it is possible to define on a
channel-specific basis the maximum permissible number of part program blocks which may
be pre-decoded during processing.
