Parameters 315
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 wake-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.
100.00 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
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
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
0.0…999.9 kWh Energy savings in kWh. 10 = 1 kWh
