  1. Hello, Just started to play with Omron CPM2A plc using the CX-Programer software. I have a project where I demo a ball screw actuator with SmartStep servo. Can't figure out the Origin search routine, (Home routine) code for the CPM2A. Software: CX-programer PLC: CPM2A transistor OutPut Servo: SmartStep 100W Switch for actuator Alt.1: -1pcs. Motor side Origin switch (CCW) N.C (NormalClosed) PNP -1pcs. End side Switch (CW) N.C. (NormalClosed) PNP Switch for actuator Alt.2: -1pcs. Motor side Origin switch (CCW) N.C (NormalClosed) PNP -1pcs. Proximity Origin switch (Home switch) N.C (NormalClosed) PNP -1pcs. End side (CW) N.C. (NormalClosed) PNP Boath Alt. OK. Other plc's like CJ1M-CPU21..., C200... have the Origin search functions pre-programed. Have someone done this routine?
