After the pulses for stepper motor control have been generated via the outputs and were
output to the power section of the stepper motor, the pulses will be converted into an axial
motion by the power section of the stepper motor. The connection between the conveyors is
driven by the axis.
Steps
In this chapter you will perform the following steps:
● You create the technological object "Axis".
● You configure the technological object "Axis", by:
– assigning a pulse generator to the technological object.
– Configuring the pulse generator as PTO (Pulse Train Output).
– Assigning a high-speed counter to the pulse generator (is automatically selected).
● You create two motion control instructions:
– One to enable the axis (MC_Power).
– One for relative positioning of the position of the light barrier "LS3"
(MC_MoveRelative).
