[etherlab-users] Controlling motors in position controller mode

Hi, I am using the EL7031 to control a motor using the position controller mode but I am having issues. My steps per revolution are at the default of 200 using the setting 8010:06. My cyclic function executes every 10ms. Every time the function executes, the target position (7010:11) is increment

Hi, We have been using EtherCAT master 1.5.2 for about two years. We have successfully implemented 4 machines. Each has 5 Kollmorgen AKD servo drives and some Beckhoff IO modules. Now we are implementing a new machine. On this machine we usually get the following messages: ... "system2count()

Re: [etherlab-users] Controlling motors in position controller mode

Hi, This module supports “64-fold” micro stepping. So the number of counts per revolution for the Target Position is 200*64 = 12800 steps per revolution. Regards, Graeme. From: etherlab-users [mailto:etherlab-users-boun...@etherlab.org] On Behalf Of Paul Mulligan Sent: Tuesday, 26 January 20

Hi, The “system_time_base less than system time” is from the rtai_rtdm_dc example code. In the example it looks like system_time_base is initialised to zero and adjusted by a maximum of +-1001 each cycle. A value of -58905492552780 indicates that system_time_base is not being correctly initia
