P1-11 V/F Mode Voltage Boost
0.0 Drive Rating Dependent %
Voltage boost is used to oncrease the applied motor voltage at low output frequencies, in order to improve low speed and
starting torque. Excessive voltage boost levels may result in increased motor current and temperature, and force ventilation
of the motor may be required.
An automatic setting (Auto) is also possible, whereby the Fenner QD:Neo will automatically adjust this parameter based on
the motor parameters measured during an autotune.
