Description
Set / reset enable signals This command switches the enabling signals on the axis.
The states:
• Drive enabled
• pulses (power section enabled) enabled
are indicated by the corresponding "LEDs" in the monitoring
area.
To permit the motion commands to be processed at the axis, all
enable signals must be assigned and the followup mode
canceled.
Position controller enable is ignored in the case of velocity-
controlled axes.
Details check
box
When this box is set, some of the commands open a separate
parameter input box.
When this check box is reset, you can enter selected
parameters in the adjacent input boxes.
Velocity-controlled axis
motion
This command specifies that the axis must start in velocity-
controlled mode.
A velocity setpoint is preset to which the axis can accelerate
along a set velocity ramp. The command can be issued for all
axis types. Positioning and synchronization axes are operated
in velocity-controled mode.
You start the axis starts by clicking "Start" or "Jog".
Position-controlled axis
motion
This command specifies that the axis must start in position-
control mode.
A velocity setpoint is preset at which the axis can accelerate
along a set velocity ramp. The command can be issued for all
positioning and synchronization axes.
Start the axis starts by clicking "Start" or "Jog".
Relative / absolute
positioning
The command positions the axis (positioning or synchronized
axis). You can enter an absolute or relative position value.
Modulo axes can also be positioned along the "shortest path".
You start the axis by clicking "Start".
