(0)  Hi, I have CU320 and s120 power drives. I have 4 synchronisation (physical motor) axes, joined to one positioning (virtual) axis. I have two limit switches on each physical axis, connected to CU and configured in starter as Hardware Limit Switch for corresponding axis. So far so good, but: How can I stop all motors, when first limit switch is hit? I would need to configure somehow also virtual axis' limit switches. Suggested option was to set "Report error of master axis" to "Actual values", under Technology -> Axes -> <my axis> -> Monitoring -> tab Synchronous operation. This does not work. I figured out a way, to connect same signals to External Alarm 1,2 and 3 to my CU, but this way kills possibility to move away from hit limit switch. I am using techonogy version 4.1.1, so sfb 480 and further are out of question. Thanks === Edited by looka @ 6/12/2012 12:40 PM [GMT ] === added tech version
