Registration and the MAR Instruction: Catching a Mark at Speed on a Kinetix 5700 A Kinetix 5700 inverter latches a registration event with ±3 µs accuracy and 700 ns repeatability, and its propagation delay is compensated to zero. At 1.5 m/s that accuracy figure is 4.5 µm of position uncertainty. The photoeye in front of … Read more
Soft Travel Limits, Hard Limits and the Overtravel That Faults a Kinetix Axis A registration input on a Kinetix 5700 inverter gets a 12.0 µs pulse reject filter. The overtravel input, on the same IOD connector and the same silicon, gets the 20 ms nominal debounce that every other input function gets. At 500 mm/s … Read more
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
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
