EoE error message with Beckhoff TwinCAT

Question:

Why does an EtherCAT EoE error message appear for i750 & i950 when starting the EtherCAT master?

Answer:

Error message in TwinCAT
EoE Init cmd type 2 failed with result 0x0001 - Unspecified error: 'eoe init'

The error message states that the configured EoE IP address, consisting of

Ethernet address
Subnet mask
gateway

was rejected by the Lenze Servo Drive because it may not be assigned according to IP address rules!

The following IP address ranges may not be used or are not used by the device series i7. are rejected by the i750 and i950 device series:

169.2541.0 - 169.254.254.255
127.0.0.x
0.0.0.0

z. B. incorrect subnet masks
255.255.249.0 => Binary 1111 1111 1111 1111 1111 1001 0000 0000
255.255.17.0 => Binary 1111 1111 1111 1111 0001 0001 0000 0000

The attached screenshots show the assignment of the IP address in TwinCAT on the one hand and the error message in TwinCAT on the other.
This occurs primarily in TwinCAT if no IP address has been assigned to the ECAT master and the system searches for an IP address range itself.
