Special operating modes
• Following mode
In following mode, the position / velocity controllers of the drive are disabled.
Inherent motions or dynamic breaking is not possible at the axis. The actual
position value and the velocity setpoint are updated. This allows you to detect
external triggering of axis motions.
Following mode is not possible at virtual axes.
• Simulation mode
The simulation mode is used to test the programmed sequences in the PLC
without moving the axis in the process, based on Trace recordings.
This mode is only available for physical axes.
In simulation mode, all axes must be connected and fully functional. An axis is
simulated internally by setting the actual values equal to the setpoint values. In
simulation mode, the following error is always zero.
