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
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 specifi-
cally approves operation at the higher frequency.
