Setting The Motion Control Station; Canopen Communication - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Setting the Motion control station

The transmission data from the station specified as the Motion control station in the engineering tool is assigned to the Motion
control area, and control can be performed by setting the axis, etc.
Note that transmission data assigned to the Motion control area cannot be referenced from the CPU module in link refresh,
etc.

CANopen communication

CANopen communication is a function used to control a device that is compatible with the CANopen profile.
The CANopen communication can control a device that supports the CANopen profile with the SDO communication by
transient transmission and the PDO communication by cyclic transmission. The SDO communication reads/writes objects
non-periodically by using the SLMPSND instruction to send a command for accessing the CAN application object to the target
device station.
For details of a command for accessing the CAN application object, refer to the following.

For details of the SLMPSND instruction, refer to the following.

The PDO communication reads/writes objects defined with the PDO mapping by using the cyclic transmission.
The PDO mapping of the Motion control station is automatically set according to the device connected with the Motion
module. For details of the PDO mapping of the Motion control station, refer to "Devices Compatible with CC-Link IE TSN" in
the following manual.
MELSEC iQ-F FX5 Motion Module/Simple Motion Module User's Manual (Application)
The PDO mapping of the standard station is set in "Batch Setting of PDO Mapping" or "PDO Mapping Setting".
The contents of the PDO mapping setting are sent to slave devices when the cyclic transmission with slave devices starts.
