Sequence of Operation to Commission an Induction Motor

1. Read and follow all safety warnings and cautions in this

manual.

2. At installation, ensure:

That the SVX9000/SPX9000 and motor are connected to

ground.

That the utility and motor cables are in accordance with

the installation and connection instructions as detailed

starting on Page 5.

That the control cables are located as far as possible

from the power cables as detailed starting on Page 21.

That control cable shields are connected to protective

ground. That no wires make contact with any electrical

components in the SVX9000/SPX9000.

That the common input of each digital input group is

connected to ground or +24V of the I/O terminal supply

or an external supply as detailed here.

3. Check the quality of the cooling air as detailed starting

on Page 3.

4. Check that moisture has not condensed inside the

SVX9000/SPX9000.

5. Check that all START/STOP switches connected to the

I/O terminals are in the STOP state.

6. Connect the SVX9000/SPX9000 to the utility and switch

the power on. For the initial power-up, you will enter the

Startup Wizard, which will guide you through

application selection and basic parameter setup. See

the Startup Wizard on Page 46 for more information.

After completing the Startup Wizard, proceed to

step 8. If this is not the initial power-up, the keypad

will default to the Operate Menu. Depress the ENTER

button for 2 seconds to enter the Parameter Menu.

Proceed to step 7.

7. Ensure that the Group 1 parameters match the

application by setting, at minimum, the following

parameters to match the motor nameplate:

Nominal voltage of the motor.

Nominal nameplate frequency of the motor.

Nominal nameplate full load speed of the motor.

Motor nominal current.

Motor power factor.

Motor type (select PM motor in Group 6 of special app)

8. Perform either Test A or Test B without the motor

connected to the SVX9000/SPX9000.

Test A—Control from the Control Panel

Apply input power to the SVX9000/SPX9000.

Press the keypad START button.

If not in the Operate Menu, go to the Monitoring Menu

and check that the output frequency follows the keypad

reference.

Press the keypad STOP button.

Test B—Control from the I/O Terminals

Apply input supply power to the SVX9000/SPX9000.

Change control from the keypad to the I/O terminals

using the LOCAL/REMOTE button.

Start the drive by closing the START/STOP input on

DIN1.

Change the frequency reference setting on AI1.

If not in the Operate Menu, go to the Monitoring Menu

and check that the output frequency follows the

frequency reference.

Stop the drive by opening the START/STOP input on

DIN1.

9. Disconnect all power to the SVX9000/SPX9000. Wait

until the cooling fan on the unit stops and the indicators

on the panel are not lit. If no keypad is present, check

the indicators in the control panel cover. Wait at least

ﬁve more minutes for the DC bus to discharge. Connect

the motor to the SVX9000/SPX9000. If possible, perform

a startup test or ID run with the motor connected to the

SVX9000/SPX9000 but not connected to the process. If

the SVX9000 must be tested with the motor connected

to the process, perform it under no-load conditions.

10. Repeat Test 8A or 8B to check operation of the motor

without the process or load. Note proper motor current,

voltage, and direction of shaft rotation. If an encoder

card is installed, set encoder parameters in the expander

board menu and monitor frequency and speed from the

encoder board. Frequency should match output

frequency of the drive with a positive value for forward

direction. If encoder frequency is opposite, change

motor phase order, encoder connection, or select

“invert” on the expander board menu. For many pump

or fan applications, no tuning is required. If further tuning

is necessary, perform the tuning while the motor is

disconnected from the process.
