In overtravel state, the motor can still operate in opposite direction.
6.7.2 Enabling/disabling overtravel function
Pt50A = t.X (Allocation of forward prohibition input (P-OT) signal) and Pt50A = t.X (Allocation
of reverse prohibition input (N-OT) signal) are used to allocate ovetravel signals to input pins. If overtravel
function is not needed, wiring for overtravel function is not required.
