5 Applied Instructions and Basic Usage
5.10.8 Manual Pulse Generator Mode
1. Motion control function block
The motion control function block T_MPG is used to enable a manual pulse generator mode. The value
of the Axis input pin indicates an axis number. The motion of the axis specified follows the operation of
a manual pulse generator. The relation between the position of the axis specified and the input pulses
generated by the manual pulse generator used is determined by the RatioNum input pin and the
RatioDen input pin. The speed at which the manual pulse generator used responds depends on the
value of the Tacc input pin and the value of the Tdec input pin. Users can set the Tacc input pin and the
Tdec input pin in the motion control function block T_AxisSetting1.

The terminals in the solid frame are for the first axis. The terminals in the dotted frame are for the
second axis and the third axis. (DVP20PM00M supports the third axis.)
