How do DVP-EH2 and DVP-28SV series PLC change the zero-return direction when reaching LSP/LSN? Or are there any other commands able to do so?DVP-EH2 and DVP-28SV do not have LSP/LSN defining function. The proper solution will be to write a ladder program that commands motor to conduct with Y1 signal. For example:
DVP-ES2/EH2 has negative limit function which will enable M1307 and trigger X5 when executed. For more information, please refer to DVP-ES2/EX2 application manual.
