Learning Basic Features
4.13 V/F(Voltage/Frequency) Control
Configure the inverter’s output voltages, gradient levels and output patterns to achieve a target
output frequency with V/F control. The amount of of torque boost used during low frequency
operations can also be adjusted.
4.13.1 Linear V/F Pattern Operation
A linear V/F pattern configures the inverter to increase or decrease the output voltage at a fixed
rate for different operation frequencies based on V/F characteristics. A linear V/F pattern is
partcularly useful when a constant torque load is applied.

Description
DRV-18 Base Freq
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.
DRV-19 Start Freq
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 (0 Hz).
