As it can be observed, as soon as BRKS signal goes to ON, L144 timer starts to count. On the other
hand, as soon as mechanical brake opens torque (output current) increases but some time is needed
to stabilize torque at zero speed. When L144 timer is elapsed, because torque is over L147 level,
output function LCO is going to ON state. After 0.2 s, in order to make sure brake is closed before
current is removed, LCO alarm is issued.
