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
Driving a Motor from a ControlLogix: From a Rung to a Turning Shaft on a Kinetix 5700 A 2198-D032-ERS3 inverter, a VPL-B1303C motor on one Hiperface DSL cable, and a 1756-L83E that has never carried a motion group. Two rungs will turn that shaft — an MSO and then an MAM — and neither is … Read more
MCD and MCCP: Changing the Speed of a Move in Flight, and What MCCP Actually Calculates An MCD that lowers Decel from 1000 mm/s² to 200 mm/s² 1.72 seconds into an absolute move catches the axis at 391.6 mm with 131 mm/s still to lose. Stopping at the new rate takes 42.8 mm and only … Read more
MAG and Gearing Two Axes: The Ratio, the Slave, and What Happens on a Fault A MAG with a Ratio of 0.5 and Clutch enabled, fired at a slave whose master is already running at 600 mm/s, ramps the slave to 300 mm/s in 0.30 seconds at 1000 mm/s² and leaves it permanently 44.9 mm … Read more
MAH and Homing a Kinetix Axis: The Switch, the Marker, and the Home That Lands in the Wrong Place A home-to-switch-then-marker sequence at a Home Speed of 25 mm/s and a Home Return Speed of 5 mm/s takes just over four seconds on a 2198-D032-ERS4 axis, and 1.5 of those seconds are spent crawling back … Read more
MAM Against MAJ on a Logix Axis: A Move That Ends and a Move That Does Not An absolute MAM to 400.000 mm at 250 mm/s, with 1000 mm/s² either side of the cruise, sets its .PC bit 1.83 seconds after the rung goes true. An MAJ at 120 mm/s on the same axis sets … Read more
