44.16 Brake reopen delay Defines a minimum time between brake closure and a
subsequent open command.
0.00 s
0.00 … 10.00 s Brake reopen delay. 100 = 1 s
44.17 Brake fault function Determines how the drive reacts upon a mechanical brake
control error.
Note: If parameter 44.07 Brake acknowledge selection is set
to No acknowledge, acknowledgement status supervision is
disabled altogether and will generate no warnings or faults.
However, the brake open conditions are always supervised.
Fault
Fault The drive trips on a 71A2 Mechanical brake closing failed /
71A3 Mechanical brake opening failed fault if the status of the
acknowledgement does not match the status presumed by the
brake control logic.
The drive trips on a 71A5 Mechanical brake opening not
allowed fault if the brake open conditions cannot be fulfilled
(for example, the required motor starting torque is not
achieved).
0
Warning The drive generates a A7A1 Mechanical brake closing failed /
A7A2 Mechanical brake opening failed warning if the status of
the acknowledgement does not match the status presumed by
the brake control logic.
The drive generates a A7A5 Mechanical brake opening not
allowed warning if the brake open conditions cannot be
fulfilled (for example, the required motor starting torque is not
achieved).
1
Open fault Upon closing the brake, the drive generates a A7A1
Mechanical brake closing failed warning if the status of the
acknowledgement does not match the status presumed by the
brake control logic.
Upon opening the brake, the drive trips on a 71A3 Mechanical
brake opening failed fault if the status of the
acknowledgement does not match the status presumed by the
brake control logic.
The drive trips on a 71A5 Mechanical brake opening not
allowed fault if the brake open conditions cannot be fulfilled
(for example, the required motor starting torque is not
achieved).
2
44.18 Brake fault delay Defines a close fault delay, ie. time between brake closure
and brake close fault trip.
0.00 s
0.00 … 60.00 s Brake close fault delay. 100 = 1 s
44.21 Filter time brake
torque memory
Defines a filtering time for parameter 44.02 Brake torque
memory (actual torque value used as open torque reference).
100 ms
0…100 ms Filtering time. 100 = 1 ms

45 Energy efficiency
Settings for the energy saving calculators.

45.01 Saved GW hours Displays the energy saved in GWh compared to direct-on-line
motor connection. This parameter is incremented when 45.02
Saved MW hours rolls over.
This parameter is read-only (see parameter 45.21 Energy
calculations reset).
