Chapter 1 Functional Descriptions
Over Speed
This function is used to increase the speed above the motor’s rated frequency.
For example, a motor’s rated frequency is 50 Hz and the target frequency is
60 Hz. To accelerate the motor to the desired frequency, do the following:
1. Set the motor’s rated frequency with parameter Rated Output Frequency
(P460) to “50”.
2. Set the target frequency with parameter Maximum Output Frequency
(P466) to “60”.
3. Enable this function by setting parameter Over Speed Enable (P467) to “1”.
