4. OPERATION
4.5.3 Automatic operation by BCD (3 digits
2) input with the MR-DS60 digital switch
The positioning is executed based on the positioning data set with the MS-DS60 digital switch and the selected
speed command. For the connection example of the MR-DS60 digital switch to the servo amplifier, refer to
section 3.2.2.
(1) Parameter setting
Set the parameter No. Po10 to ensure that the BCD (3 digits
2) can be used. Set the parameters
referring to the following table as required.

Forward rotation start (ST1) ON: rotates
in the CCW direction.
Reverse rotation start (ST2) ON: rotates
in the CW direction.
1 Forward rotation start (ST1) ON: rotates
in the CW direction.
Reverse rotation start (ST2) ON: rotates
in the CCW direction
(2) Operation
When the positioning data is set with the MS-DS60 and the forward rotation start (ST1) is turned ON,
operation is performed in the forward direction for the moving distance of the positioning data under the
conditions of the motor speed and the acceleration and deceleration time constants set in the point tables
selected with SP0 to 3. In the incremental command system, operation is performed in the reverse direction
when the reverse rotation start (ST2) is turned ON.
Select the point table with SP0 to 3 as shown below and execute the positioning based on the set motor
speed, acceleration and deceleration time constants.
