Test B: Control From The Keypad; Start-Up Test; Identification Run - Danfoss VACON NXS Series Operating Manual

Operating Guide | VACON® NXS/NXP Air-cooled
Procedure
1. Turn the Start/Stop switch to ON position.
2. Change the frequency reference (potentiometer).
3. Do a check in the Monitoring menu M1 that the value of output frequency changes the equivalent quantity to the frequency
reference.
4. Turn the Start/Stop switch to OFF position.

9.4.2.2 Test B: Control from the Keypad

Context:
Do this RUN test when the control mode is keypad.
Procedure
1. Change the control from the control terminals to the keypad. For the instructions, see
2. Push the Start button on the control panel.
3. Go to the Keypad control menu (M3) and Keypad Reference submenu (see
reference, use the Browser buttons.
4. Do a check in the Monitoring menu M1 that the value of output frequency changes the equivalent quantity to the frequency
reference.
5. Push the Stop button on the control panel.

9.4.3 Start-up Test

Context:
Do the start-up tests without the load, if possible. If this is not possible, make sure that it is safe to do each test before doing it. Make
sure that the other workers near know about the tests.
Procedure
1. Make sure that all Start/Stop switches are in Stop positions.
2. Turn the mains switch ON.
3. Check the rotation direction of the motor.
4. If close loop control is used, make sure that the encoder frequency and direction are the same as the motor direction and
frequency.
5. Do again the Run test A or B, see
6. If the motor was not connected in the start-up test, connect the motor to the process.
7. Make the identification run without the motor running. If close loop control is used, make the identification run with the motor
running. See 9.4.4 Identification

9.4.4 Identification Run

The Identification Run helps to tune the motor and the drive-related parameters. It is a tool to be used in commissioning to find the
best possible parameter values for most drives. The automatic motor identification calculates or measures the necessary motor
parameters for the best possible motor and speed control. For more information on the Identification Run, see VACON
Application Manual, parameter ID631.
