Example
*1. Timing of detection.
Level detection: activated when the bit is set or cleared.
Edge detection: activated at OFF-to-ON transition.
Point
• The priority order of each bit becomes as follows. When several bits are turned on, the bit with higher
priority becomes valid. However, if several bits of the positioning operations (b6, b8 to b15) turn on, the
operation is not executed, and the operation command multiple selection error occurs.
• When another operation command is turned on during operation, the operation command turned on later is
ignored, and no error will occur.
• Create the sequence program as each bit (b0, b6, b8 to b11, b13 to b15) of the edge detection always
turns off after being turned on. Without turning off each bit, the second or further operations cannot be
executed.
• Error reset (b0) is executed only when an error is occurring.
• Do not use the forward limit (b2)/reverse limit (b3) for any purposes other than limiting.
• The positioning operations (b6, b8 to b15) become valid when all bits of the BFM#25 (b0 in the normal
status, excluding the b2/b3 and b7 opposite from the operation direction) are turned off and then on.
7.4.7 [BFM#54, #53] Target address change value
Set the target address change value that is used in the target address change function.
→ For details on the target address change function, refer to Section 6.7.
Point
Value is in user units and includes the position data multiplier.
