NOTES:
1. Auto restart requires a constant ON command (such as via a digital input).
2. P1200 flying start must be used in cases where the motor may still be
turning, such as after a brief input power break, or can be driven by the
load.
3. A supply power brownout is when the power is interrupted and reapplied
before the operator panel display has gone dark. It is a very short supply
power break where the DC link has not fully collapsed
4. A supply power blackout is when the operator panel display has gone
dark before the power is reapplied. It is a long supply power break where
the DC link has fully collapsed.
