Axisx_Run Subroutine - Siemens SIMATIC S7 System Manual

Open loop motion control
12.6 Subroutines created by the Motion wizard for the Axis of Motion
Turn on the Abort parameter to command the Axis of Motion to stop execution of this
command and decelerate until the motor comes to a stop.
The Error parameter (Page 659) contains the result of this subroutine.
The C_Pos parameter contains current position of the Axis of Motion. Based upon the units
of measurement, the value is either a number of pulses (DINT) or the number of engineering
units (REAL).
The C_Speed parameter contains the current speed of the Axis of Motion. Based upon the
units of measurement, the value is either a number of pulses/second (DINT) or the
engineering units/second (REAL).

Turn on the EN bit to enable the subroutine. Ensure that the EN bit stays on until the Done
bit signals that the execution of the subroutine has completed.
Turn on the START parameter to send a RUN command to the Axis of Motion. For each
scan when the START parameter is on and the Axis of Motion is not currently busy, the
subroutine sends a RUN command to the Axis of Motion. To ensure that only one command
is sent, use an edge detection element to pulse the START parameter on.

Description
The AXISx_RUN subroutine (Run Profile) commands the Axis of Motion
to execute the motion operation in a specific profile stored in the con-
figuration/profile table.
