In case SAFETY ENABLE is issued before ENABLE maximum allowed time
before system goes into interblock

Table 2 Safety Intervention times.
Looking at the Enable signals evolving dynamically in time, the allowed input conFiguretions are
less than those highlighted in Table 1: in order to prevent pwm pulses to be applied suddenly
ENABLE signal will always follow SAFETY ENABLE or, at least be applied before 4ms within it.
Should ENABLE come first before SAFETY ENABLE, ADL drive goes into interlock block and it
will be necessary to disable and issue ENABLE high again in order to reactivate ADL.
Following figures are describing the dynamics of STO. function:
