3.2 Applying Power

WARNING
HIGH VOLTAGE!
Frequency converters contain high voltage when
connected to AC mains. Installation, start-up, and
maintenance should be performed by qualified
personnel only. Failure to comply could result in death or
serious injury.
WARNING
UNINTENDED START!
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency
converter, motor, and any driven equipment must be in
operational readiness. Failure to comply could result in
death, serious injury, equipment, or property damage.
1. Confirm that the input voltage is balanced within
3%. If not, correct input voltage imbalance before
proceeding. Repeat this procedure after the
voltage correction.
2. Ensure that optional equipment wiring, if present,
matches the installation application.
3. Ensure that all operator devices are in the OFF
position. Panel doors should be closed or cover-
mounted.
4. Apply power to the unit. DO NOT start the
frequency converter at this time. For units with a
disconnect switch, turn to the ON position to
apply power to the frequency converter.

3.3 Basic Operational Programming

3.3.1 Required Initial Frequency Converter
Programming
Frequency converters require basic operational
programming before running for best performance. This
requires entering motor nameplate data for the motor
being operated and the minimum and maximum motor
speeds. Enter data in accordance with the following
procedure. Parameter settings recommended are intended
for start-up and checkout purposes. Application settings
may vary. See chapter 4 User Interface for detailed
instructions on entering data via the keypad.
Enter data with power ON, but before operating the
frequency converter.
1. Press [Quick Menu] on the keypad.
2. Use the navigation keys to scroll to Quick Start
and press [OK].

3.4 Auto Tune

Auto tune is a test procedure, which measures the
electrical characteristics of the motor to optimize compati-
bility between the frequency converter and the motor.

Select language and press [OK]. Then enter the
motor data in parameters P-02, P-03, P-06, P-07,
F-04, and F-05. The information can be found on
the motor nameplate.
Parameter P-07 Motor Power [kW] or
parameter P-02 Motor Power [HP]
Parameter F-05 Motor Rated Voltage
Parameter F-04 Base Frequency
Parameter P-03 Motor Current
Parameter P-06 Base Speed
Enter parameter F-01 Frequency Setting 1 and
press [OK].
Enter parameter F-02 Operation Method. Local,
Remote, or Linked to Hand/Auto. In local the
reference is entered on the keypad, and in
remote that reference is sourced depending on
parameter F-01 Frequency Setting 1.
Enter the accel/decel time in parameter F-07 Accel
Time 1 and parameter F-08 Decel Time 1.
For parameter F-10 Electronic Overload enter Elec
OL Trip 1 for Class 20 overload protection. For
further information, see
chapter 2.5.1 Requirements.
For parameter F-17 Motor Speed High Limit [RPM]
or parameter F-15 Motor Speed High Limit [Hz]
enter the application requirements.
For parameter F-18 Motor Speed Low Limit [RPM] or
parameter F-16 Motor Speed Low Limit [Hz] enter
the application requirements.
Set parameter H-08 Reverse Lock to Clockwise,
counterclockwise or Both directions.
In parameter P-04 Auto Tune select Reduced Auto
Tune or Full Auto Tune and follow on-screen
instructions. See chapter 3.4 Auto Tune.
The frequency converter builds a mathematical
model of the motor for regulating output motor
current. The procedure also tests the input phase
balance of electrical power. It compares the
motor characteristics with the data entered in
P-02, P-03, P-06, P-07, F-04, and F-05.
The motor shaft does not turn and no harm is
done to the motor while running the Auto tune.
