I am using an AKD2G in Profile Velocity mode and sending new setpoints at about 10 Hz. Every time the drive recieves a new velocity setpoint, the current spikes and making a clicking sound. I have tried tuning the AR filters to use a Low Pass cutoff slightly below 10 Hz but it either goes unstable or doesn't affect the current spike. What other drive parameters can I adjust to prevent current spikes at setpoint changes. I have attached a xlsx file with the scope output showing the current spikes.
AKD2G Servo Drive Firmware for CANopen, EtherCAT, EtherNet/IP, PROFINET, and Analog devices. This firmware complies with recently revised U.S. and E.U. export regulations (E.U. Dual-Use Regulation 428/2009, and U.S. Dual-use regulation EAR Category 3 under ECCN3A225).
This application note demonstrates AKD2G parameter access from a S7-1500 PLC using the SinaPara function block for multi-parameter access and the SinaParaS for single parameter access. Please sign into your Siemens Support Portal to download these function blocks and follow their instructions for importation. The link and versions are controlled by Siemens and may change at any time. This application note uses the DriveLib V600 for SIMATIC STEP 7 Professional V16 for S7 1200/S7 1500.

WorkBench is a Graphical User Interface that allows configuration from different Kollmorgen devices. Includes full installer: the application with complete help files and the .NET Framework required by the application. Supports AKD and AKD2G devices. For more information regarding features, see the AKD Workbench Release Notes.
The controlled motion of any given axis of a machine will require the AC mains to be dropped after completion of an emergency-stop (NEC - Category 1). The necessary NEC stop category is determined based on the machine builder’s safety audit. This application note is only valid for Stop Category 1.
Dropping the AC mains, as well as other circuits, can provide the redundancies required for meeting certain safety ratings. A time-off relay is commonly used to allow for a time delay between starting a controlled stop function and dropping the STO, HW enable, and/or AC mains, etc.
This document outlines the setup in the AKD2G to use Actions with the command buffer feature with a time-delay to switch off the output relay (Digital Output 9) to drop AC mains power. This can eliminate the need for an external time-off relay.
