Set the parameters of group 1 (See Vacon All in One Application Manual) according to the
requirements of your application. At least the following parameters should be set:
- motor nominal voltage
- motor nominal frequency
- motor nominal speed
- motor nominal current
You will find the values needed for the parameters on the motor rating plate.

Perform run test without motor
Perform either Test A or Test B:
A Controls from the I/O terminals:
a) Turn the Start/Stop switch to ON position.
b) Change the frequency reference (potentiometer)
c) Check in the Monitoring menu M1 that the value of Output frequency changes according to
the change of frequency reference.
d) Turn the Start/Stop switch to OFF position.
B Control from the control keypad:
a) Change the control from the I/O terminals to the keypad as advised in Chapter 7.3.3.1.
b) Push the Start button on the keypad.
c) Move over to the Keypad control menu (M3) and Keypad Reference submenu (Chapter
7.3.3.2) and change the frequency reference using the Browser buttons

.
d) Check in the Monitoring menu M1 that the value of Output frequency changes according to
the change of frequency reference.
e) Push the Stop button on the keypad.

Run the start-up tests without the motor being connected to the process, if possible. If this is not
possible, secure the safety of each test prior to running it. Inform your co-workers of the tests.
a) Switch off the supply voltage and wait up until the drive has stopped as advised at Chapter 8.1,
step 5.
b) Connect the motor cable to the motor and to the motor cable terminals of the frequency
converter.
c) See to that all Start/Stop switches are in Stop positions.
d) Switch the mains ON
e) Repeat test 8A or 8B

Perform the Identification Run. The Identification Run is a part of tuning the motor and the drive
specific parameters. It is a tool for commissioning with the aim to find as good parameter values
as possible for most drives. The automatic motor identification calculates or measures the motor
parameters that are needed for optimum motor and speed control. For closer details on the
Identification Run, see All in One Application Manual, par. ID631.
11 Connect the motor to the process (if the startup test was run without the motor being connected)
a) Before running the tests, make sure that this can be done safely.
