@cliff.pennalligen: Brilliant write up.
@ABD.HAS00: I am assuming that the on/off pulse frequency generated by the PLC is too slow. The inductance of the motor does not "smooth out" the current enough. The motor "sees" an on/off pulse. The best solution would be to use a driver (H-bridge). A inductor based low pass filter (https://industrial.panasonic.com/ww/ss/technical/b4) may also work -- but I am still concerned about using the PLC outputs directly. |
