Chapter 4 Parameters|
10 - 07
Primary Low Pass Filter Time
Settings
This parameter determines primary Low Pass filter time.
Output frequency of PID controller will filter by primary low pass function. This function could
decrease change of output frequency. A long primary low pass time means filter degree is high
and vice versa.
Unsuitable primary low pass filter time setting may cause system oscillation.
10 - 08
PID Feedback Signal Range
Settings
This parameter setting could allow the maximum of PID deviation.
If PID function is normally, it should control the detective value to target value accurately in the
certain time. If AC drive can't control deviation in the 10-08 setting range during 10-07 setting
time, it means PID feedback control is abnormal. The treatment is set as 10-10.
10 - 09
PID Feedback Signal Fault Treatment Time
Settings
This parameter is to set the detection time of abnormal PID derivative. If PID deviation
detection time is set to 0.0, the function is disabled.
10 - 10
PID Feedback Signal Fault Treatment
Settings
This parameter is to set treatment of the abnormal PID deviation.
