Position Error and Following Error on a Kinetix Axis: What a Trend Says That FLT S54 Does Not

by
A trend of position error in millimetres across one MAM move on a 2198-D020-ERS3, rising on the acceleration ramp, flat during the slew, spiking to about 24 millimetres at 0.56 seconds, flat at 10.9 millimetres through the slew and returning to zero at rest, with the Position Error Tolerance drawn as a dashed line at 21.8 millimetres

Position Error and Following Error on a Kinetix Axis: What a Trend Says That FLT S54 Does Not A 2198-D020-ERS3 threw FLT S54 – POSN ERROR at 14:02 and again at 14:19, and the fault-code spreadsheet describes it in one sentence: the position error of the position control loop exceeded Position Error Tolerance for longer … Read more

Tuning a Kinetix 5700 Axis: Load Ratio, Bandwidth and the Autotune That Lies

by
Step response of the same position loop at three bandwidths: 8.2 Hz settling inside two percent at 91 ms, 41.7 Hz at 22 ms, and 101.7 Hz peaking at 112.6 percent before settling at 9 ms, all against a target line at 100 percent

Tuning a Kinetix 5700 Axis: Load Ratio, Bandwidth and the Autotune That Lies Loop Response on the General page of a Kinetix axis is a three-item dropdown, and on a drive with the default 1.5 ms model time constant it moves the position loop between 8.2 Hz and 101.7 Hz. That is a factor of … Read more
