9.4.2 RUN Test without Load
Do either Test A or Test B.
Test A: Controls from the control terminals
Test B: Control from the control panel
9.4.2.1 Test A: Controls from the Control Terminals
Do this RUN test when the control mode is I/O terminals.
Procedure
Turn the Start/Stop switch to ON position.
Change the frequency reference (potentiometer).
Do a check in the Monitoring menu
M1
that the value of output frequency changes the equivalent quantity to the frequen-
cy reference.
Turn the Start/Stop switch to OFF position.
9.4.2.2 Test B: Control from the Keypad
Do this RUN test when the control mode is keypad.
Procedure
Change the control from the control terminals to the keypad. For the instructions, see
8.4.3 Changing the Control Mode
.
Push the Start button on the control panel.
Go to the Keypad control menu (
M3
) and
Keypad Reference
submenu (see
reference, use the Browser buttons.
Do a check in the Monitoring menu
M1
that the value of output frequency changes the equivalent quantity to the frequen-
cy reference.
Push the Stop button on the control panel.
9.4.3 Start-up Test
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
Make sure that all Start/Stop switches are in Stop positions.
Turn the mains switch ON.
Check the rotation direction of the motor.
If close loop control is used, make sure that the encoder frequency and direction are the same as the motor direction and
frequency.
Do again the Run test A or B, see
If the motor was not connected in the start-up test, connect the motor to the process.
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 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 pa-
rameters for the best possible motor and speed control. For more information on the Identification Run, see VACON
