Firmware on an AKI-CDB Panel can be loaded either by Ethernet or by USB.

Setup if Loading via Ethernet 

If loading via Ethernet, make sure that the computer IP address is in the same range as the AKI - CDB Panel and that the subnet mask is the same.  The computer will need to be set with a static IP address.  If you need to set it as static or change the IP address you can do it through the Network Properties:


The following chart outlines the networks (field buses) supported by the PCMM and PDMM and the key  parameters of each.


The following document outlines the EtherCAT based networks that KAS supports and key parameters that define each of the  network.


Attached is a sample program showing basic UDP communications between two KAS PxMM controllers. The concepts here can easily be applied to communicating between a PxMM controller and a PC or other non-Kollmorgen product.

With PxMM UDP communications:

The AKD's X11 Service Port is a standard 10/100 Base Ethernet port. AKD will auto-negotiate the bit rate and supports full-duplex mode only. Unplugging and reconnecting the cable signals the drive to auto-negotiate again (so at that point the bit rate may change, IP address is updated if on DNS, etc.) Keep in mind the speed of the processor does not compute at this rate. The data packages are sent at the 100 Mbit rate, but the processor has to interpret the data.

I know Kollmorgen offers ethernet cables for ethercat communications. I can't seem to find any part numbers on the catalog nor quote assistant. Does anyone know where I can find this information?

Setting up an Ethernet network can be frustrating if you don’t understand the basics.  A network is just the communication connection between two or more devices.  These devices can be computers, PLC’s, servo drives, HMI’s, sensors, cameras…anything that supports Ethernet communication.  The network is established by assigning an identity to each device.  This is done by using what is called an “IP Address”.  Each device on a network must have an IP Address, and that address must be different from the addresses of all other devices on that network.  The network

Modbus TCP is a communication protocol that is available on all models of the AKD drive ( except the AKD-P-NAPN or AKD-P-NBPN ( Profinet ).  The communication is supported on Ethernet physical hardware, the X11 Ethernet port on the top of the drive.

Normally, the Workbench software is used to connect to and configure the AKD drives.  However, there may be some instances where Workbench can't be used or where another communication method is preferred for troubleshooting purposes, etc.  Two terminal programs that can be used to communicate with the AKD are Hyperterminal and PuTTY.  Both of these support TCP/IP communication and can be used in the same way as the Terminal screen in Workbench.
