    During spindle switching control or speed range switching control, there was a conflict between the
    switch request signal (SPSL or RSL) and the power line state confirmation signal (MCFN, MFNHG,
    or RCH, RCHHG). Switching unit (magnetic contactor for power line switching) may be defective.
    Connections of magnetic contactor may be loose. Make sure the Parameters for the power line state
    signals related to the spindle switch control and output switch control are set correctly.
