# Memory size for backward motion (P-STUP-00033)

P-STUP-00033 | Memory size for backward motion
Description | This parameter defines the memory size in bytes used for backward motion on the path. During start-up, the NC checks whether the required minimum size is available. If this is not the case, a warning is output and the memory size is set to the required minimum value. If the size is set to 0, the “forward/ backward motion on the path” function is not available. The maximum size is only limited by the resources available on the PC.
Parameter | fb_storage_size[i] where i = 0 to 11 (maximum number of channels: 12, application-specific)
Data type | UNS32
