TwinCAT Motion Control PTP implements Motion Control for point-to-point movements in software. The axes
are represented by axis objects and provide a cyclic interface, e.g. for the PLC. This axis object is then
linked to a corresponding physical axis. In this way, the most diverse axis types with the most diverse
fieldbus interfaces can be connected abstractly with the axis objects, which always offer an identical
configuration interface. The control of the axes can be configured in various conformations (position or
velocity interface) and various controllers. The axes are configured in TwinCAT Engineering.

Run Mode, Controller Enable, Moving Axes Manually
For moving axes manually …
· … restart the TwinCAT System in Run Mode.
The
· Online dialog for an NC-axis
is suitable as
· commissioning visualization
for a first commissioning of an axis.
WARNING | Axis Position at a First Commissioning
Usually, prior to a first commissioning the axis position displayed is wrong. Therefore, pre
ceding a first commissioning a homing sequence should be carried out or as a zero position
offset a position bias should be applied. |
After you have restarted the TwinCAT System in Run Mode, within the Online dialog for the NC-axis
Standard (Mapping via Encoder and Drive) the checkboxes
· Ready and
· NOT Moving,
each in the field Status (log.), are checked.
For moving axes manually …
· … set the controller enable, …
· move the axes with the buttons F1 - F6 and F8 - F9.
Setting the Controller Enable
· For setting the controller enable the servo drive has to be ready for operation.
Ready · If checked, the servo drive is ready for operation.
· Generally, the simulation axis is ready for operation.
Within the Online dialog of an NC-axis within the field Enabling the Set button opens the Set Enabling dialog
for setting the controller enable for the corresponding axis.
Controller · Necessary for the positional control to be active.
· Without controller enable the controller is not active.
· If linked to PLC: Corresponds to the Enable input of the MC_Power function
block.
Feed Fw · Without feed enable in positive direction the axis cannot be started in positive
direction.
· If the axis moves in positive direction while the feed enable in positive direction
is taken away, then the axis is stopped.
If afterwards the feed enable is enabled again undoing this previous taking
away, then the axis does not begin to move automatically again.
· If linked to PLC: Corresponds to the Enable_Positive input of the MC_Power
function block.
Feed Bw · Without feed enable in negative direction the axis cannot be started in negative
direction.
· If the axis moves in negative direction while the feed enable in negative direction
is taken away, then the axis is stopped.
If afterwards the feed enable is enabled again undoing this previous taking
away, then the axis does not begin to move automatically again.
· If linked to PLC: Corresponds to the Enable_Negative input of the MC_Power
function block.
Override · Influences the velocity percentage of all drive commands. It is 0 ≤ Override
≤ 100.0.
