To prepare to run the motor in the powerup test, this section will show how to configure the necessary parameters:
1. Select the digital operator as the source of motor speed command (A001=02).
2. Select the digital operator as the source of the RUN command (A002=02).
3. Set the motor base frequency (A003) and AVR voltage of the motor (A082). 4. Set the motor current for proper thermal protection (b012).
5. Set the number of poles for the motor (H004).
The following series of programming tables are designed for successive use. Each table uses the previous table’s final state as the starting point. Therefore, start with the first and continue programming until the last one. If you get lost or concerned that some of the other parameters setting may be incorrect, refer to “Restoring Factory Default Settings” on page 6-8.
Prepare to Edit Parameters – This sequence begins with powering ON the inverter, then it shows how to navigate to the “A” Group parameters for subsequent settings. You can also refer to the “Keypad Navigation Map” on page 2-26 for orientation throughout the steps.

1. Select the digit al operator for Speed Command – The inverter output frequency can be set from several sources, including an analog input, memory setting, or the network, for example. The powerup test uses the keypad as the speed control source for your convenience. Note that the default setting depends on the country.

2. Select the digital operator for RUN Command –
To RUN command causes the inverter to accelerate the motor to the selected speed. The Run command can arrive from various sources, including the control terminals, the Run key on the keypad or the network. In the figure to the right, notice the Run Key Enable LED, just above the Run key. If the LED is ON, the Run key is already selected as the source, and you may skip this step. Note that the default setting depends on the country.

3. Set th e Motor Base Frequency and AVR voltage of the motor – The motor is designed to operate at a specific AC frequency. Most commercial motors are designed for 50/60 Hz operation. First, check the motor specifications. Then follow the steps below to verify the setting or correct it for your motor. DO NOT set it greater than 50/60 Hz unless the motor manufacturer specifically approves operation at the higher frequency.
Action Display Func./Parameter
(Starting point)
A002 Run command source setting
Press the U key once. A003 Base frequency setting
Press the SET key.
60.0.
or
50.0
Default value for the base frequency. US = 60 Hz, Europe = 50 Hz
Press the U / V key to select 60.0 Set to your motor specs (your display may be different)
Press the SET key. A003 Store parameter, returns to “A003”
CAUTION: If you operate a motor at a frequency higher than the inverter standard default setting (50Hz/60Hz), be sure to check the motor and machine specifications with the respective manufacturer. Only operate the motor at elevated frequencies after getting their approval. Otherwise, there is the danger of equipment damage.
Set the AVR Voltage Setting – The inverter has an Automatic Voltage Regulation (AVR) function. It adjusts the output voltage to match the motor’s nameplate voltage rating. The AVR smoothes out fluctuation in the input power source, but note that it does not boost the voltage in the event of a brown-out. Use the AVR setting (A082) that most closely matches the one for your motor.
• 200V class: 200 / 215 / 220 / 230 / 240 VAC • 400V class: 380 / 400 / 415 / 440 / 460 / 480 VAC
To set the motor voltage, follow the steps on the following table.

= 460VAC (HFU)
Press the U / V key to select A215 Set to your motor specs (your display may be different)

4. Set the Motor Current –The inverter has thermal overload protection that is designed to protect the inverter and motor from overheating due to an excessive load. The inverter’s uses the motor’s current rating to calculate the time-based heating effect. This protection depends on using correct current rating for your motor. The level of electronic thermal setting, parameter B012, is adjustable from 20% to 100% of the inverter’s rated current. A proper configuration will also help prevent unnecessary inverter trip events.
Read the motor’s current rating on its manufacturer’s nameplate. Then follow the steps below to configure the inverter’s overload protection setting.

A082 AVR voltage select
Press the ESC key. b001 First “B” Group parameter selected Press the U key and hold until Æ b012 Level of electronic thermal setting Press the SET key. b160 Default value will be 100% of inverter rated current
Press the U / V key to select b140 Set to your motor specs (your display may be different)

5. Set the Number of Motor Poles – The motor’s internal winding arrangement determines its number of magnetic poles. The specification label on the motor usually indicates the number of poles. For proper operation, verify the parameter setting matches the motor poles. Many industrial motors have four poles, corresponding to the default setting in the inverter (H004).
Follow the steps in the table below to verify the motor poles setting and change if necessary (the table resumes action from the end of the previous table.)
Action Display Func./Parameter
(Starting point)
b012 Level of electronic thermal setting
Press the ESC key two times H001 “H” Group selected Press the U key three times H004 Motor poles parameter
Press the SET key. H004
2 = 2 poles
4 = 4 poles (default) 6 = 6 poles
8 = 8 poles 10 = 10 poles
Press the U / V key to select H004 Set to your motor specs (your display may be different)
Press the SET key. H004 Store parameter, returns to “H004” This step concludes the parameter setups for the inverter. You are almost ready to run the motor for the first time!
TIP: If you became lost during any of these steps, first observe the state of the PRG LED. Then study the “Keypad Navigation Map on page 2-26 to determine the current state of the keypad controls and display. As long as you do not press the SET key, no parameter will be changed by keypad entry errors. Note that power cycling the inverter causes it to power up Monitor Mode, displaying the value for D001 (output frequency). The next section will show you how to monitor a particular parameter from the display. Then you will be ready to run the motor.
