from the serial network.
Timer Output Closed: Timer output.
Fref/Fout Agree2 Closed: When drive output frequency equals the frequency reference ±L4-04.
Fref/Set Agree 2 Closed: When the drive output frequency is equal to the value in L4-03 ±L4-04.

Reverse Dir Closed: Drive is running in the reverse direction.
Open: Drive has entered the baseblock state (no output voltage).
Dur Flt Restart Closed: An automatic restart is performed
Closed: oL1 is at 90% of its trip point or greater. An oH3 situation also triggers
