VFD-F Series

5-71

Settings 0.0~2.5 Sec Unit: 0.1

 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

Factory Setting: 600.0

Settings 0.0~6550.0 Unit:0.1

 This parameter setting could allow the maximum of PID deviation.

 If PID function is normal, 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 10-09 setting time,

FbL warning will pup-up and it means PID feedback control is abnormal. The treatment is set as

10-10.

10 - 09

PID Feedback Signal Fault Treatment Time

Factory Setting: 0.0

Settings 0.0~3600.0 Sec Unit: 0.1

 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



Factory Setting: 01

Settings 00: Warn and RAMP stop

01: Warn and COAST stop

02: Warn and keep operating

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

10 - 11

PID Minimum Output Frequency



Factory Setting: 01

Settings 0: By PID controller

1: By AC drive

 This parameter can decide the source of PID output minimum frequency when AC drive enters PID

sleep process. If it is set to 0, minimum output frequency should be set by PID. If it is set to 1 and

01-08 is 0, the output frequency is equal to the value of 01-05 setting. If it is set to 1 and 01-08 is not

0, the output frequency is equal to the value of 01-08 setting.
