Control variable
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module and using the "single-phase" regulation mode, this parameter
can be used to select the phase used for voltage regulation. You can select
the following options:
▪
L1/N or L1/L2
▪
L2/N or L2/L3
▪
L3/N or L3/L1
To set the control variable, proceed as follows:
1.
Go to
Settings > Parameters > Measurement > Control variable
.
2.
Select the option you want.
3.
Press the
Accept
button to save the modified parameter.
Regulation mode
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module, you can use this parameter to set whether you want 1-phase
voltage regulation or voltage regulation to the average value of the 3 phases.
You can select the following options:
▪
Single-phase: Voltage is automatically regulated to one selected phase.
Limit value monitoring, line drop compensation, and parallel operation
also take place on the selected phase using the circulating reactive cur-
rent minimization method.
▪
Average value regulation: Voltage is automatically regulated to the aver-
age of the 3 phases. Limit value monitoring, line drop compensation,
and parallel operation also take place using the circulating reactive cur-
rent minimization method to the average of the 3 phases.
If you activate the average value regulation option, automatic voltage regu-
lation is blocked should the voltage or current measurement of one of the 3
phases fail.
To set the regulation mode, proceed as follows:
1.
Go to
Settings > Parameters > Measurement > Regulation mode
.
2.
Select the option you want.
3.
Press the
Accept
button to save the modified parameter.
Control of the motor-drive unit (optional)
You can use the following parameters to configure control of the motor-drive
unit. You can set the following:
▪
Switching pulse
▪
Motor runtime
▪
Switching direction
