11. MR-D01 EXTENSION I/O UNIT
(1) Parameter setting
Set the parameters to use BCD (3-digit × 2) inputs with [Pr. Po10]. Refer to the following table and set
the parameters as necessary.

(2) Operation
Set position data with the MR-DS60 (6-digit digital switch) and turn on ST1 (Forward rotation start) to
move the travel distance of the position data in the forward direction with the rotation speed, acceleration
time constant, and deceleration time constant set in the point table selected with SPD1 (Speed selection
1) to SPD4 (Speed selection 4). In the incremental value command method, turning on ST2 (Reverse
rotation start) moves the travel distance in the reverse direction.
Select point tables as follows with SPD1 (Speed selection 1) to SPD4 (Speed selection 4) and execute
the positioning based on the set rotation speed, acceleration time constant, and deceleration time
constant.
In this case, the position data set to the point table is not used.
