Description
dr.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.
dr.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.
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.
