Hello Higgor Olipe, I don't know the exact reason of the time delay. There is a CPU manual for the S7-400 which describes the reaction time and cycle time of the CPU. https://support.industry.siemens.com/cs/ww/de/view/53385241/en Perhaps your program is too long or has blocks which needs a lot of time for execution. A check could be to create a new project only with the blocks for the motor control. A general hint: motor control by using the time isn't the best method to control a motor. There is no guaranty of reproducibility. If there is no strong need of reproducibility or exact motor/actor position, a time controlled motor can be used. |
