5.4 Parameters AC axes
In this paragraph, the parameters for axes with AC drives are discussed.
When using AC drives, it is possible to program 1-side positioning or 2-side positioning. Beside
this, it must be indicated whether a one-speed or 2-speed motor drive is used.
With these parameters you can optimize the positioning accuracy of the AC-axis:
• Breakpoint high speed (Bfs)
• Breakpoint low speed (Bss)
• Overrun (OR)
• Overrun wait time
• Stop time (T)
Two side positioning:
Figure 5.4.a
When the axis approaches the programmed position the motor output is switched off when the
actual position is within Bss and the stop time T has elapsed.
The stoptime should be less then the time between two successive encoder pulses.
