Program Example
b3, b2: Interrupt input setting
The interrupt signals used for interrupt inputs in the interrupt 1-speed positioning operation, external
command positioning operation, interrupt stop operation or interrupt 2-speed positioning operation are set.
b5, b4: Position data multiplier
Multiplier for the position data written for the zero-point address (BFM#14, #13), the target address I
(BFM#18, #17), the target address II (BFM#22, #21), the current address (BFM#27, #26), and the target
address change value (BFM#54, #53).
Example of setting: When b5, b4 = (1, 1)
When the target address I (BFM#18, #17) = 123, the actual address or the travel distance becomes as follows.
Motor system of units: 123×10

= 123,000 PLS
Machine system of units, Combined system of units: 123×10

= 123,000 (μm, mdeg, 10

= 123 (mm, deg, 10
-1
inch)
b6: Acceleration/deceleration mode
Set the acceleration/deceleration mode.
b6 = 0: Use trapezoidal acceleration/deceleration.
b6 = 1: Use approximate S-shaped acceleration/deceleration.
b7: Variable speed operation acceleration/deceleration setting
Set whether acceleration/deceleration is set for the variable speed operation.
b7 = 0: Variable speed operation without acceleration/deceleration
b7 = 1: Variable speed operation with acceleration/deceleration
b8: Pulse output format
Set the pulse output format. When it is set, the ON/OFF condition of the pulse output terminal FP/RP changes
as follows.
b8 = 0: Forward pulse (FP)/Reverse pulse (RP)
b8 = 1: Pulse (PLS)/Direction (DIR)
b9: Rotation direction
Set the rotating direction. It is used for the initial setting. It is not necessary to change the rotating direction for
each actual operation.
b9 = 0: The current address increases with forward pulse (FP).
b9 = 1: The current address decreases with forward pulse (FP).
