How to control the step motor with s7-200, how to control the yield to the motor, how to stop?
The pulse output and direction of 200PLC are not related. You can see it from the number of pulses that you want to see from >. You can write the direction control program in front of the PLS command and immediately.
Use the continuous pulse output command (speed control instruction) from the s7-200. Stop also using the instructions, detailed in your instruction manual for Siemens.
You always turn, suppose you are using I0.1 normally open contact PLS instruction as well as the setting of the office, then keep I0.1 closed, in a single period of the office after the execution, will continue to perform the same single section of the office, have been implemented. Stop, if you make a ladder diagram again, normally open contacts I0.2 is connected, connected to change back SMB67 will control mode is set to prohibit pulse output, as well as SMD72 will regarding the pulse number is set to 0, then PLS instructions with respect to OK.
The number of pulses in a single segment is zero. Pulse mode reset pulse output point is invalid. It will be overridden immediately
