A subnet mask is a bit mask used to define a subnet of an Ethernet network.  It acts like a filter to only allow devices with certain IP addresses to communicate.

Subnets are used to specify which devices can communicate with which other devices on an Ethernet network.

So here's my story. Boss decided I'm going to start programming our custom built machines. He said," Theres a computer over there, go use it." 

We use TRIO with Motion Perfect v4, Proface HMIs with GP-PRO EX, Kollmorgen drives and servos (at least sometimes). So I've got everything wired up and the drive (AKD-P) is giving me fault F401 no matter what I do. Our servo is a Kollmorgen AKM 52L. The drive and servo are connected via a Kollmorgen Hybrid Cable AKD. 

This video series comprises of 16 videos as a complete training on AKD Ethernet IP Communications. Videos 1 though 7 are essential and the remaining videos can be viewed in order or the user can pick and choose a topic of interest or one that pertains to something specific in their application.

In the top right-hand corner of the following link there is a right arrow that allows the user to index from 1 to 16 on the video playlist.

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?
