4. OPERATION
4.5.4 Automatic operation by BCD (3 digits
2) input with the programmable controller
The positioning is executed the positioning based on the positioning data set with the programmable controller
and the selected speed command. For the connection example of the programmable controller to the servo
amplifier, refer to section 3.2.3.
(1) Parameter setting
Set the parameter No.Po10 to enable to use the BCD (3 digits
2) input and the strobe (STRB). Set the
parameters referring to the following table as required.

Make the I/O devices required for the
BCD input valid. For devices to be valid,
refer to section 3.4.
Strobe signal 0
Make sure to set the strobe (STRB).
A strobe signal is required if the
programmable controller is used.

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 programmable controller and the forward rotation start (ST1) is
turned ON, operation is performed in the forward rotation direction for the moving distance of the
positioning data under the conditions of the motor speed and the acceleration and deceleration time
constants set to 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.
