Hello folks,

I have problem with random booting drive S300 - S343 hw rev 03.01 fw 3.75, after power on. See picture below, right one from drives. Problematic status in red rectangle.

Hello there!

I have a problem with my S300 (6A) servo amplifier, firmware – v5.86_ND0, hardware revision – 4.10.

It successfully worked with the motor on which SinCos Encoder W&S was installed (FBTYPE = 7), but after replacing my motor’s feedback to an absolute one (FBTYPE = 33 BiSS-C Renishaw), the servo amplifier started to generate Overspeed Error (F08), sometimes Warning n23, less often Feedback Loss (F04).

New Features

  • FailSafe over EtherCAT (FSoE) "Black Channel" Communication
  • AKD2G Drive Integration:
    • Backup/Restore
    • AKD2G with SMM options #2 (basic) and #3 (advanced)
  • Robotic Kinematic Transforms: T-Bot, H-Bot, and Gantry
  • IDE Ease-of-Use Enhancements:
    • New Project Comparison view
    • New Create Variable dialog box, also available from the Editors
    • PLCopen Axes Groups in the Project Tree

For more details, please see the attached release note.

Good afternoon!
I have a circular motor that must rotate an object in the range from a certain degree to a certain degree with a certain step and a pause between steps. 

For example, from -90 degrees to +90 degrees in increments of 5 degrees and a pause between steps of 1 second.
What is the best way for me to assign motion tasks?

I was thinking of a way to set a separate motion task for each step with a pause between them, but I'm afraid that I will not have enough motion tasks if the range is larger and the step is smaller.

How can I download S300 firmware for HW version 3.0

in site, i couldn't find it.


Good day!

I need help with tuning my Digital Servo Amplifier SERVOSTAR 300.

I use self-developed rotary motor + AksIM off-axis rotary absolute encoder (Renishaw) with BiSS-C interface + Kollmorgen S306.

This set of components works well when encoder cable length less than 5 meters, but i need use it with 15 meters encoder cable length.

Setting GEARI with PDO (OPMODE 4)


we have a small problem using a S300 (FW 5.18) in OPMODE 4(el. gear). We want to change the input gear parameter GEARI with the object 2040(as PDO), but the new value will active only after coldstart. There is a possibility to change GEARI with the object 353E and the value will active immediately without coldstart, but the PDO-mapping for this object is not possible.

Does anybody know any option to change the GEARI on the fly with PDO mapping?

Thank you.

Often users need to upload the parameters out of a failed drive and recommission a spare drive with the archived parameters.

The attached documents detail these procedures.

Note the documents assume you have the same model, hardware and firmware revisions. Attempting to clone a drive with

differences will likely yield errors when you attempt to download to the spare drive.

Errors that occur on download will need to be checked one by one using the ASCII reference guide to determine reason and impact on your application.

Good day. How can I use LA11dca13bka10da00 absolute magnetic encoder system BISS-C interface with my linear motor?
