2050 (Hex) - MEMOBUS/Modbus Write Request
Drive MEMOBUS/Modbus registers can be written using this object. The data must be written in byte 1 and 2 of
Subindex 1, and 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, only
one ENTER command must be sent after the last parameter change. This will activate all changed parameters. This
ENTER command can be used without limitations.
To execute this ENTER command, “save” (73H + 61H + 76H + 65H) must be written in object 2060H, subindex 0.
Read value: 0x00000001 (Execute on command)
MEMOBUS/Modbus register: 0x0910 (Un-Memorized ENTER command)

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, only one ENTER command must be
sent after the last parameter change. This will activate all changed parameters. This ENTER command can be applied
approximately 100,000 times and should be used only when necessary.
To execute this ENTER command, “save” (73H + 61H + 76H + 65H) must be written in object 2070H, subindex 0.
Read value: 0x00000001 (Execute on command)
MEMOBUS/Modbus register: 0x0900 (Memorized ENTER command)
Note: Write access to this object is only allowed in the EtherCAT Pre-Operational state.
