Issue In high-speed motion control applications, using standard PLC logic to activate digital outputs based on an axis's position can introduce scan-time latency, resulting in delayed and inaccurate machine timing. Resolution Implement a CAM Switch configuration utilizing the Modicon M660 Motion Controller and the Edge IO NTS Motion Module in EcoStruxure Machine Expert Logic Builder. This configuration maps precise hardware-level position tracking to deterministic output modules.

Issue Users need to properly add and configure an LXM32S drive so it can communicate and operate over a Sercos network controlled by a Modicon M660 Motion Controller within EcoStruxure Machine Expert Resolution To integrate the drive, add a generic "SERCOS Drive" to the SercosMaster node and change its working mode to "Physical". Update the generic Sercos identification by setting the Vendor Device ID to "LXM32" and the Vendor Code to "1". Finally, configure the scaling by setting the Increment Resolution to "131072" (matching the drive's default). Once downloaded to the controller and the Sercos state reaches Phase 4, the drive can be operated using standard PLCopen Function Blocks Disclaimer The views and opinions expressed in this article are those of the author(s) and do not necessarily reflect the official policy or position of Schneider Electric.  

Issue In high-speed motion control applications using the Modicon M660 Controller, standard PLC logic scan times can introduce latency. This causes inaccuracies when trying to record the exact position of a moving axis or when trying to establish a precise home reference position based on a physical sensor trigger. Resolution Implement a TouchProbe configuration utilizing the Edge IO NTS NTSEDT0800 timestamped discrete input module in EcoStruxure Machine Expert Logic Builder. This specialized hardware captures a precise, hardware-level timestamp the exact microsecond an input changes state. By integrating this module with standard PLCopen Function Blocks MC_TouchProbe, MC_AbortTrigger and FB_HomingTouchProbe, the system can execute highly accurate position monitoring and homing sequences that are completely independent of the PLC cycle time.
