Configuring Manufacturer Specific CANopen Objects
This section describes the configuration of manufacturer specific objects that support content selection.
Selectable Object Content
All parameters, monitors and other control registers in the drive are represented by their MEMOBUS/Modbus register.
The EtherCAT option card allows the user to select the content of some manufacturer specific objects by mapping them
to any of the drives MEMOBUS/Modbus registers, so that those objects can be set up to contain the value of drive
parameters, monitors, and other MEMOBUS/Modbus registers (e.g. alarm and fault status, etc.). Refer to the drive
Technical Manual for details on available MEMOBUS/Modbus registers.
Selecting the Object Content
Objects with selectable content have the following structure.
To map the content of a specific MEMOBUS/Modbus register of the drive to subindex 1 of an object, the MEMOBUS/
Modbus register address must be written to subindex 2 of the object.
Examples
• In order to map the drive output power monitor (U1-08, 0047 (Hex)) to output object 21A0 (Hex), write 0047 (Hex) to
subindex 2 of object 21A0 (Hex).
• In order to map the frequency reference 1 (d1-01, 0280 (Hex)) to input object 2090 (Hex), write 0280 (Hex) to
subindex 2 of object 2090 (Hex).
• In order to map the input terminal status (U1-10, 0049 (Hex)) and output terminal status (U1-11, 004A (Hex)) to output
object 21F0 (Hex) (4 byte), write 0049 (Hex) to the higher, and 004A (Hex) to the lower word of object 2090 (Hex),
subindex 2.
