10.3 Tables and BFM No. Allocation
Stores the table operation information to the 20SSC-H buffer memory. There are 2 BFM types, one for
operation by individual axis (X/Y axis) and the other for XY-axis simultaneous operation.
Note
• The save command (BFM #523 b2 to b4) writes and stores the BFM table information in the 20SSC-H flash
memory.
→ For a program example, refer to Subsection 7.1.9
• The default value for table information is "-1."
• The 20SSC-H stores the table number in execution in the executing table number (BFM #16, #116).
Caution for setting
Selecting the following patterns in the operation information requires two table rows.
• 2-speed Positioning operation
• Interrupt 2-speed constant quantity feed
