36 • 750-636 [DC Drive Controller]Function DescriptionWAGO-I/O-SYSTEM 750I/O-ModulesP3:The duration of phase P3 results from the total duration and the subtraction ofall other phases: P3 = Ptot –(P1 + P2 + P4 + P5).P4:A waypoint in the direction of travel before the setpoint position determinesthe start of phase P4. The waypoint is always calculated from theShutDown_Distance parameter, relative to the setpoint position. The pulseduty cycle for PWM of phase P4 is set via CurrentControl_PWM parameter.P5:Phase P5 defines the deceleration ramp and is set via RampTime_STOPparameter. If its value is 0, the process is stopped immediately according toStopMode.Additionally, it is possible to enable CurrentControl_PWM during a‘MovePos’ or ‘MoveNeg’ approach via CurrentControl_ON=1 control bit.This can also be done during a positioning drive in phase P3.2.1.1.9.10.2 Drive Versions Including Change to Lower SpeedExample 15, "ShutDown_Distance is reached in phase P3":P1 P20 %P4P3 P550 %100 %PWM Duty CycleRampTime_START CurrentLimit_Time RampTime_STOPCurrentLimit_PWMPWM 100 %CurrentControl_PWMShutDown_Distance > PrestopPrestopSet Point PositionFig. 2.1.1-22: Example 15, "ShutDown_Distance is reached in phase P3" g063624eIn this example, the individual phases do not overlap due to configuration andare executed sequentially from P1 to P5. If the distance between the startposition and the setpoint position decreases, phase 3, and even phase 2, maybe skipped by the moving cycle. The following two figures illustrate thisexample. The CurrentControl_ON control bit is disabled.
