01-12 No-load oscillation suppression gain
Range
【0.0~200.0】%
In the situation of no power and no-load that damping is low, active and reactive energy
fluctuations will greatly stimulate the inverter output current oscillations. Appropriately adjusting
01-12 can suppress oscillation by frequency gain. Compensation is based on the percentage
of the load current corresponds to the motor rated current. The adjustment for 01-14 can be
increased or decreased every time about 5% to 10%.
01-13 Motor Hunting Prevention Coefficient
Range
【1~8192】
01-14 Motor Hunting Prevention Gain
Range
【0~100】%
01-15 Motor Hunting Prevention Limit
Range
【0.0~100.0】%
In the situation of no power and no-load that damping is low, active and reactive energy
fluctuations will greatly stimulate the inverter output current oscillations. Appropriately adjusting
01-12 can suppress oscillation by compensating V/F voltage command.
Compensation is
based on high-pass filtering and the load current value, then it is multiplied by the gain limiting,
finally, it is added by the V / F output voltage. The adjustment for 01-14 can be increased or
decreased every time about 5% to 10%.
01-13 filter coefficients corresponding filter time = 2048 / set point ms, such as 01-13 = 800, then
filtering time = 2048/800 = 2.56ms.
01-15 of 100% corresponds to 150V (100,200V series) / 300V (400V series).
01- 16 Auto-Torque Compensation Filter Coefficient
Range
【0.1 ~ 1000.0】ms
01- 17 Auto-torque Compensation Gain
Range
【0~ 100】%
01- 18 Auto-torque Compensation Frequency
Range
【1.30 ~ 5.00】Hz
Auto-torque Compensation function must be in SLV mode to auto tune so that inverter can get
the value of stator resistor. Inverter Without Auto-Torque Compensation If 01-17=0. 01-17
compensation is based on V/F maximum output voltage and the load current, The adjustment
for 01-14 can be increased or decreased every time about 5% to 10%.
Parameter 01-16~01-18 is for V/F mode only. SLV mode doesn’t need to adjust these
parameter because auto-tune in SLV mode will get the value of motor parameter.
