Footnote 1:
The signal "automatic restart" is generated by the sequence control.
If the voltage at the power section fails briefly in the "operating" state (see P086)
(and if automatic restart is selected, i.e. P086 > 0), the "operating" signal goes to log. "0" and
the "automatic restart" signal to log. "1" during this time.
This causes the brake to remain open during this short time without torque.
Footnote 2:
A negative value in P087 means that the signal "Open brake" is delayed with respect to the enable
for the firing pulses for the thyristor. Only this case is shown in this function diagram.
