Thank you for your in depth answer. The model behind the base object and the derived one is clear. What I do not understand is why I cannot use the Mode Forwarder Template in OES 4.11. Should I use a previous version? Latest version (1.5.3.0) im my repository requires OES5.4. Maybe version 1.4.1.0 will do. The problem would be find that version. I'm using one of the latest object releases and it contains only V1.5! ... View more

Thank you again. DriveReadyForOp is the first parameter that I thought I should try! Happy to see I was correct! ... View more

Thank you for your answer. This is what I'm doing right now (with the green option). As soon as the PLC see that the light curtain is interrupted, it set QuickStop, reset Enable and reset Execute. The axis stops with the desored deceleration (within the prescribed time, otherwise the Maximum transition time will be raised by the drive). Then, as soon as the light curtain is free again, the PLC check the axis position and jump back in the chain to the prevoius steps when the axis is enabled and the MOVE command is execute. I still need to investigate which OutImm signal check before re-enabling the drive. At the moment I have an opcon object error if I do not add a delay before enabling the drive after the OutImm.DriveEnabled value is true. I will have a station available within the next month to do some more test. For sure I'll check any axis update to see if any behaviour is changed. ... View more

Hello, thank you for this explanation.The behaviour of the axis was very similar to your description, with the exception of the deceleration. For most of the tests I did last week, the configuration was the red one. During those tests, the axis was stopped vith very high deceleration (much higher than configured Dec parameter). After I've changed the axis configuration to the green one, the deceleration in S-0-0372 was used, as you state. In August I'll work on a similar station and I'll do some more test to understand the best way to handle this situation. Since the light curtain reset the MS signal in the drive SMO, I need the axis peripheral to reset the enabling signal in order to avoid the "maximum transition time exceeded" error on the drive. At the same time, I need to intercept the axis ERROR because I don't want any error in the HMI and I'll need to re-issue the positioning command to be sure the axis is in the desired position before going on By the way, the NexeedEcRxId used in the Std is the following ObjectVersion version="2.2.10.0" ...
