Linear V/F Pattern Setting Details
Sets the base frequency. A base frequency is the inverter’s output
frequency when running at its rated voltage. Refer to the motor’s rating
plate to set this parameter value.
Sets the start frequency. A start frequency is a frequency at which the
inverter starts voltage output.
The inverter does not produce output voltage while the frequency
reference is lower than the set frequency. However, if a deceleration
stop is made while operating above the start frequency, output voltage
will continue until the operation frequency reaches a full-stop.
4.11.2 Square Reduction V/F Pattern Operation
Square reduction V/F pattern is ideal for loads such as fans and pumps. It provides
non-linear acceleration and deceleration patterns to sustain torque throughout the
whole frequency range.
