256 Actual signals and parameters
4425 PID ENABLE
DEV
Defines the level when Precharge is disabled and PID is
enabled. When the level is reached, PID is enabled. PID is
executed as parameterized. If reference ramp times are set,
they are used.
0.1%
0.0…100.0% Value in percent of the maximum feedback. 1 = 0.1%
4426 PIPEFILL
TIMEOUT
Defines the maximum time Precharge is allowed to operate.
If this time elapses, PID is preset and PID is allowed to run
as it is parameterized – with or without reference ramps.
0 = NOT
SEL
0 = NOT SEL
1…60000 s
0: NOT SEL
1…60000 s: Max. Precharge operating time 1 = 1 s
45 ENERGY SAVING Set-up of calculation and optimization of energy savings.
Note: The values of saved energy parameters 0174 SAVED
KWH , 0175 SAVED MWH , 0176 SAVED AMOUNT 1 , 0177
SAVED AMOUNT 2 and 0178 SAVED CO2 are derived
from subtracting the drive's energy consumed from the
direct-on-line (DOL) consumption calculated on the basis of
parameter 4508 PUMP POWER . As such, the accuracy of
the values is dependent on the accuracy of the power
estimate entered in that parameter.
4501 ENERGY
OPTIMIZER
Enables or disables the energy optimizer, which optimizes
the flux so that the total energy consumption and motor
noise level are reduced when the drive operates below the
nominal load. The total efficiency (motor and drive) can be
improved by 1…10% depending on load torque and speed.

OFF Disabled 0
ON Enabled 1
4502 ENERGY
PRICE
Price of energy per kWh. Used for reference when energy
savings are calculated. See parameters 0174 SAVED KWH ,
0175 SAVED MWH , 0176 SAVED AMOUNT 1 , 0177
SAVED AMOUNT 2 and 0178 SAVED CO2 (reduction in
carbon dioxide emissions in tn).

0.00…655.35 Price of energy per kWh 1 = 0.01
(Currency)
4507 CO2 CONV
FACTOR
Conversion factor for converting energy into CO2 emissions
(kg/kWh or tn/MWh). Used for multiplying the saved energy
in MWh to calculate the value of parameter 0178 SAVED
CO2 (reduction in carbon dioxide emissions in tn).
0.5
tn/MWh
0.0…10.0
tn/MWh
Conversion factor 1 = 0.1
tn/MWh
4508 PUMP POWER Pump power when connected directly to supply (DOL).
Used for reference when energy savings are calculated.
See parameters 0174 SAVED KWH , 0175 SAVED MWH ,
0176 SAVED AMOUNT 1 , 0177 SAVED AMOUNT 2 and
0178 SAVED CO2 .
It is possible to use this parameter as the reference power
also for other applications than pumps. The reference power
can also be some other constant power than a motor
connected directly on-line.
100.0%
0.0…1000.0% Pump power in percent of nominal motor power 1 = 0.1%
4509 ENERGY
RESET
Resets energy calculators 0174 SAVED KWH , 0175 SAVED
