10 - 07 | Primary Low Pass Filter Time | Unit: 0.1 | ||
| Settings | 0.0~2.5 Sec | Factory Setting: 0.0 | |
|
|
|
|
|
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 | Unit: 0.01 | |
| Settings | 0.01~160.00Hz | Factory Setting: 600.00 |
|
|
|
|
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 - 09 | PID Feedback Signal Fault Treatment Time | Unit: 0.1 | |
| Settings | 0.0~3600.0 Sec | Factory Setting: 0.0 |
| |||
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. |

|
|
|
|
|
This parameter is to set treatment of the abnormal PID deviation.
