8.2.3 General Settings, 1-0*
Define whether the frequency converter operates in open loop or closed loop.
1-00 Configuration Mode
Option:
Function:
[0] *
Open Loop
Motor speed is determined by applying a speed reference or by setting desired speed when in Hand
Mode.
Open Loop is also used if the frequency converter is part of a closed loop control system based on
an external PID controller providing a speed reference signal as output.
[3]
Closed Loop
Motor Speed will be determined by a reference from the built-in PID controller varying the motor
speed as part of a closed loop control process (e.g. constant pressure or flow). The PID controller
must be configured in par. 20-** or via the Function Setups accessed by pressing the [Quick Menus]
button.
NB!
This parameter cannot be changed when motor is running.
NB!
When set for Closed Loop, the commands Reversing and Start Reversing will not reverse the direction of the motor.
1-20 Motor Power [kW]
Range:
Function:
Application
dependent*
[Application dependant]
Enter the nominal motor power in kW according to the motor nameplate data. The default value
corresponds to the nominal rated output of the unit.
This parameter cannot be adjusted while the motor is running. Depending on the choices made in
par. 0-03
Regional Settings
, either par. 1-20
or par. 1-21
Motor Power [HP]
is
made invisible.
1-22 Motor Voltage
Range:
Function:
Application
dependent*
[Application dependant]
Enter the nominal motor voltage according to the motor nameplate data. The default value corre-
sponds to the nominal rated output of the unit.
This parameter cannot be adjusted while the motor is running.
1-23 Motor Frequency
Range:
Function:
Application
dependent*
[20 - 1000 Hz]
Select the motor frequency value from the motor nameplate data.For 87 Hz operation with 230/400
V motors, set the nameplate data for 230 V/50 Hz. Adapt par. 4-13
and par. 3-03
to the 87 Hz application.
NB!
This parameter cannot be adjusted while the motor is running.
