Program ⇒ To r que ⇒ Torque Control
This parameter Enables/Disables the Reverse Speed Limit Input control
function. When enabled and operating in the Torque Control mode, the reverse
speed limit is controlled by the terminal selected here. If Setting is selected, the
value set at
F428 is used as the Reverse Speed Limit input.
