244 Parameters
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 Energy efficiency
Settings for the energy saving calculators.
See also section Energy saving calculators (page 80 ).
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
45.04 Saved energy
Energy saved in kWh compared to direct-on-line
motor connection.
This parameter is read-only (see parameter
45.21
Energy calculations reset
).
-
0.0…214748364.7 kWh Energy savings in kWh. 1 = 1 kWh
