Volts/Hz Curve Modification (Torque Boost)
Range
【0 ~ 10.0】%
 Inverter output V/F curve settings for points B, C can be adjusted by parameter 01-10 to adjust the output
torque.
 Calculation of B, C point voltage: B point voltage = Xb × maximum output voltage, C point voltage = Xc ×
maximum output voltage (Xb, Xc see Page 4-26). When 01-10 = 0, torque boost is disabled.

No-load oscillation suppression gain
Range
【0.0~200.0】%
 During power fluctuations under a no-load condition the inverter might experience output current oscillations.
Adjusting 01-12 accordingly to suppress oscillation. Compensation is based on the percentage of the load
current relative to the motor rated current. Adjust 01-12 in steps of 5 to 10% up or down.

 During power fluctuations under a no-load condition the inverter might experience output current oscillations.
Adjusting 01-12 accordingly to suppress oscillation by compensating V/F voltage command. Compensation
is based on filtering the load current by using a high-pass filter multiplied by the gain and clamped by a limiter.
The result is added to the V/F output voltage. Adjust 01-14 in steps of 5 to 10% up or down.
 Parameter 01-13 is a filter coefficient. Filter time in ms is 2048 divided by 01-13. Example: 01-13 = 800,
then filter time = 2048 ÷ 800 = 2.56 ms.
 100% of the output limiter parameter 01-15 corresponds to 150V (100, 200V series) and 300V (400V series).
