For this axis, the parameter ‘Breakpoint slow speed’ (BSS) must be programmed. This
parameter defines the switch-off points for the axis movement. The value depends on the
known deceleration rate of the axis equipment. If the BSS is not accurate enough to reach the
programmed position, the parameter ‘Stop time’ (T) can be used for further fine-tuning of the
positioning.
If the axis is controlled through the analog output, the parameter ‘DC slow speed’ must be
programmed to a correct value.
2-speed AC axis
For a 2-speed axis, the parameter ‘axis type’ must be set to 2. This axis can be driven through
3 or 4 digital outputs or through the analog output. The axis can be controlled at two different
speed levels.

For this axis, the parameters ‘Break point low speed’ (BSS) and ‘Break point high speed’
(BFS) must be programmed. These parameters define the switch-off points for high and low
speed for the axis movement. As with the 1-speed axis, the parameter ‘Stop time’ (T) can be
used to improve positioning.
If the analog output is used for axis control, the parameters ‘DC high speed’ and ‘DC low
speed’ must be programmed at two different values. These values determine the voltage levels
at the analog output for the two different speed settings.
One side positioning:
In the explanations above, the control systems used two-side positioning. So when moving
from high to low or vice versa, positioning takes place instantly.
In some cases, it is desired to have positioning only in one direction.
