P3
:
The duration of phase P3 results from the total duration and the subtraction of all
other phases: P3 = Ptot –(P1 + P2 + P4 + P5).
P4
:
A waypoint in the direction of travel before the setpoint position determines the
start of phase P4. The waypoint is always calculated from the
ShutDown_Distance parameter, relative to the setpoint position. The pulse duty
cycle for PWM of phase P4 is set via CurrentControl_PWM parameter.
P5
:
Phase P5 defines the deceleration ramp and is set via RampTime_STOP
parameter. If its value is 0, the process is stopped immediately according to
StopMode. Additionally, it is possible to enable CurrentControl_PWM during a
'MovePos' or 'MoveNeg' approach via CurrentControl_ON=1 control bit. This is
also during a positioning motion during phase P3.

Example 15 "ShutDown_Distance is reached in phase P3":
Figure 25: "ShutDown_Distance is Reached in Phase P3"
In this example, the individual phases do not overlap due to configuration and are
executed sequentially from P1 to P5. If the distance between the start position and
the setpoint position decreases, phase 3, and even phase 2, may be skipped by the
moving cycle. The following two figures illustrate this example. The
CurrentControl_ON control bit is disabled.
