A CU240E-2 PN sits on the PROFINET IO system of a CPU 1516-3 PN/DP with G120 telegram 1 in its device view, the PLC is writing 16#047F to the control word and 8192 to the setpoint, and the motor does not move. Bit 6 of the status word is set. That bit is “switching on … Read more
Two PowerFlex 525s with 42.50 Hz on both keypads were running the takeaway at 0.500 m/s and the palletiser infeed it hands over to at 0.462 m/s, and every carton that crossed the transfer between them arrived 7.6% closer to the one in front than it had left. A 1219 mm carton that left the … Read more
P033 [Motor OL Current] on a PowerFlex 525 holds exactly one number. Land two 3 HP motors on T1, T2 and T3 and that number is now watching the pair as though they were one 6 HP machine, which leaves neither motor protected. That single parameter is the whole argument. Two standard induction motors will … Read more

What a warper, a sizing line and a stenter need from a PLC: draw ratios, dancer and load cell loops, yarn break stops and recipes on S7-1500 or Logix.
Sectional drive draws on a paper machine, the ratio calculation in ST, consistency and basis weight loops, and winder taper tension that holds.
