NOTE!
This parameter cannot be changed when the motor is running.
NOTE!
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:
4.00 kW* [0.09 - 3000.00 kW]
1-22 Motor Voltage
Range:
400. V* [10. - 1000. V]
8-14
Function:
Sets the date and time when Summertime/DST starts. The date is programmed in the format se-
lected in par. 0-71 Date Format .
Function:
Sets the date and time when Summertime/DST ends. The date is programmed in the format selected
in par. 0-71 Date Format .
Function:
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 adjustable frequency drive is part of a closed-loop control system based
on an external PID controller providing a speed reference signal as output.
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 set-ups accessed by pressing the [Quick Menu]
button.
Function:
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
Regional Settings
par. 0-03 , either par.1-20
made invisible.
Function:
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.
