Torque Limit Enable.'
This input function, when active, causes the torque loop to limit its commanded
torque to the value of the torque limit parameter.
Torque Mode Enable.'
This input function, when active, will enable analog torque mode regardless of
the previous operating mode. You should use this function to override preset
velocity mode only, since unwanted operation may result. When this input
function is inactive, the drive will immediately return to its previous operating
mode.
Brake Release.'
This input function will release the brake under all conditions. I f this input
function is active, the brake output function is switched to active (i.e. release
