E0 Group - Wobbulate Control Group - Powtran pi130 series User Manual

Code Parameter name
obvious, conversely, the effect of oscillation suppression is very week.
Amplitude limit value of
Fb.05
oscillation suppression
The large voltage boost value of oscillation suppression can be restricted by setting
Fb.05
Demarcation frequency of high
Fb.06 and low frequency of oscillation
suppression
Fb.06 is the demarcation point of function code Fb.03 and Fb.04.
Fb.07 Oscillation suppression
The oscillation suppression is for VF control, the current oscillation phenomena often
occurs when the ordinary motor runs with light load or no load, which can cause
abnormal operation of motor or even the overcurrent of inverter. When Fb.07 = 0, the
oscillation suppression will be enabled;the inverter will suppress the oscillation of
motor according to the parameters of Fb.03 to Fb.06 function group.
Fb.08 PWM selection
PWM mode 1: V/F control is less than 8Hz as the seven-stage type, greater than 12Hz
as the five-stage type.
PWM mode 2: V/F control fully uses the seven-stage type.
PWM mode 3: V/F control fully uses the five-stage type.
Fb.09 Energy-saving selection
When the motor runs at constant speed with no load or light load, the inverter detects
the load current, adjusts the output voltage, in order to automatically save energy.
Fb.10 Deadband time
