252 Parameters
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
The drive trips on a A7A5 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
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.
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

45.01 Saved GW hours 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).

0…65535 GWh Energy savings in GWh. 1 = 1 GWh
45.02 Saved MW hours Energy saved in MWh compared to direct-on-line motor
connection. This parameter is incremented when 45.03
Saved kW hours rolls over.
When this parameter rolls over, parameter 45.01 Saved
GW hours is incremented.
This parameter is read-only (see parameter 45.21 Energy
calculations reset).
