7.4  Pulse Output Function 
Together with a commercially available pulse-string input type motor driver, the pulse output 
function can be used for positioning control. 
 
NOTE
 
The pulse output function is only available with the transistor output type. 
Setting system registers 
When using the pulse output function, make sure the high-speed counter function is not 
allocated to the channel selected for pulse output.

7.4.1 Pulse Output Methods and Position Control Modes 
The pulse output method and position control mode are specified by means of the variables 
used with the positioning command.

Control is carried out using two pulses: a positive or clockwise rotation 
pulse (CW) and a negative or counterclockwise rotation pulse (CCW 
pulse).
