AKD EtherCAT Scaling for Velocity, Acceleration, and Deceleration >

This article discusses AKD EtherCAT scaling for velocity, acceleration, and deceleration commands and actual velocity.  For the position modes, FBUS.PARAM05 applies to position scaling and the scaling for velocity, acceleration, and…

AKD EtherCAT Flexible PDO Mapping Size Limitations and Padding >

The AKD drive supports flexible EtherCAT PDO mapping.  The 4 available flexible RxPDO’s (PDO data for receive direction, commands from master to drive) are mapped using objects 1600h, 1601h, 1602h, and 1603h.  Each one of these RxPDOs is…

Debugging Intermittent EtherCAT Communication Issues >

The following fault, error, and alarm are each indicative of possible cable or connection problems. F125 on the AKD, "Fieldbus Sync frames lost." E30 in KAS, "EtherCAT communication failure during operational mode." A38 in KAS, "EtherCAT missed…

KAS - Linking PDO parameters into application code >

The PDO Ethercat channel provides deterministic, fast update of parameters between the KAS controller and drives (through Ethercat). The PDO Selection Mapping tab provides an method to link PDO parameters to variables in the application code. The…
