11 Pr 10.012
Dynamic brake alarm
Dynamic brake alarm is set when the braking IGBT is active, and
the braking energy accumulator is greater than 75%.
12 Pr 10.013
Reverse direction commanded
Direction commanded is set to 1 if the Pre-ramp speed reference
(Pr 01.003) is negative and reset to 0 if the Pre-ramp speed
reference is zero or positive.
13 Pr 10.014
Reverse direction running
A 0 indicates forward direction and a 1 indicates reverse direction.
The source of this bit is Pr 02.001 for open loop mode and
Pr 03.002 for RFC-A and RFC-S modes.
14 Pr 10.015
Supply loss
Supply loss indicates that the drive has detected a supply loss from
the level of the DC bus voltage. This parameter can only become
active if supply loss ride through or supply loss stop modes are
selected.
In regen mode, supply loss is the inverse of Pr 03.007.
