Selecting Functions and Editing Parameters
In order to run the motor for the powerup test, this section will show how to:
• select the inverter's maximum output frequency to the motor
• set the value of parameter F_01 to the output frequency for the powerup test
• select the keypad as the source of the RUN command
• set the number of poles for the motor
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 settings may be incorrect, refer to "Restoring Factory Default Settings"
on page 99.
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.
Setting the Motor Base Frequency – 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 in the table below to verify the setting or
correct for your motor. DO NOT set it for greater than 50/60 Hz unless the motor
manufacturer specifically approves operation at the higher frequency.
