2040 (Hex) - MEMOBUS/Modbus Read Request
This object can be used to read out the content of drive MEMOBUS/Modbus registers. The address of the MEMOBUS/Modbus must be written in
byte 3 and 4 of Subindex 1, bytes 1 and 2 have to be set to 0. After sending a MEMOBUS/Modbus Read Request to the drive, the MEMOBUS/
Modbus register content can be read out from object 2140H.
For more details on MEMOBUS/Modbus address and data, refer to the MEMOBUS/Modbus/Modbus Data Table in Appendix C of the technical
manual for the drive.
2050 (Hex) - MEMOBUS/Modbus Write Request
Using this object, drive MEMOBUS/Modbus registers can be written. The data must be written in byte 1 and 2 of Subindex 1, the MEMOBUS/
Modbus address must be written in bytes 3 and 4. After sending a MEMOBUS/Modbus Write Request to the drive, the response can be read from
object 2150H.
For more details on MEMOBUS/Modbus address and data, refer to the MEMOBUS/Modbus Data Table in Appendix C of the technical manual for the drive.
2060 (Hex) - MEMOBUS/Modbus Unlimited ENTER Command
Depending on the drive parameter H5-11 setting, an ENTER command must be used to activate drive parameters changed via MEMOBUS/Modbus
Write Commands. The Unlimited ENTER command activates parameters in the drive RAM only. If the drive power is cycled, parameter changes
are lost. If more than one parameter has been changed, it is enough to send only one ENTER command after the last parameter change. Doing so
will activate all changed parameters. This ENTER command can be used without limitations.
To execute this type of ENTER command, “save” (73H + 61H + 76H + 65H) has to be written in object 2060H, subindex 0.
2070 (Hex) - MEMOBUS/Modbus Limited ENTER Command
Depending on the drive parameter H5-11 setting, an ENTER command must be used to activate drive parameters changed via MEMOBUS/Modbus
Write Commands. The limited ENTER command activates parameters in the drive’s RAM and saves them to the EEPROM. When power supply
loss occurs or the power supply is cycled, the drive will operate using the saved parameters. If more than one parameter has been changed, it is
sufficient to send only one ENTER command after the last parameter change. Doing so will activate all changed parameters. This type of ENTER
command can be applied approximately 100,000 times and should be used only when necessary.
To execute this type of ENTER command, “save” (73H + 61H + 76H + 65H) has to be written in object 2070H, subindex 0.
Note: Write access to this object is only allowed in the Powerlink
pre-operational state.
