ABB ACS180 - Energy Efficiency

Parameters 253
44.08 Brake open delay Defines the brake open delay, ie. the delay between the
internal open brake command and the release of motor
speed control. The delay timer starts when the drive has
magnetized the motor. Simultaneously with the timer start,
the brake control logic energizes the brake control output
and the brake starts to open.
Set this parameter to the value of mechanical opening
delay specified by the brake manufacturer.
0.00 s
0.00…5.00 s Brake open delay. 100 = 1 s
44.13 Brake close delay Specifies a delay between a close command (that is,
when the brake control output is de-energized) and when
the drive stops modulating. This is to keep the motor live
and under control until the brake actually closes.
Set this parameter equal to the value specified by the
brake manufacturer as the mechanical make-up time of
the brake.
0.00 s
0.00…60.00 s Brake close delay. 100 = 1 s
44.14 Brake close level Defines the brake close speed as an absolute value.
After motor speed has decelerated to this level, a close
command is given.
10.00 rpm
0.00…1000.00 rpm Brake close speed. See par.

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).
-
0…999 MWh Energy savings in MWh. 1 = 1 MWh
45.03 Saved kW hours Energy saved in kWh compared to direct-on-line motor
connection.
If the internal brake chopper of the drive is enabled, all
energy fed by the motor to the drive is assumed to be
converted into heat, but the calculation still records
savings made by controlling the speed. If the chopper is
disabled, then regenerated energy from the motor is also
recorded here.
When this parameter rolls over, parameter 45.02 Saved
MW hours is incremented.
This parameter is read-only (see parameter 45.21 Energy
calculations reset).

0.0…999.9 kWh Energy savings in kWh. 10 = 1 kWh
