Chapter 1 Outline of EzSQ
1.1 Outline
Easy sequence function (EzSQ) can built a simple sequence function by making the program with programming
software ProDriveNext. In the program, it is possible to change the I/O function and the parameter setting value.
1.2 Corresponding Model
- SJ700 series - WJ200 series - L700 series - SJ700B series
1.3 Specifications
The table below lists the programming-related specifications of the easy sequence function.
