VFD-F (CURVE).cdr

VFD-F Series This parameter determines primary Low Pass filter time. Output frequency of PID controller will filter by primary low pass function. This functioncould decrease change of output frequency. A long primary low pass time means filterdegree is high and vice versa. Unsuitable primary low pass filter time setting may cause system oscillation.10 - 08 PID Feedback Signal Range Factory Setting: 600.0Settings 0.0~6550.0 Unit:0.1 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 inthe certain time. If AC drive can’t control deviation in the 10-08 setting range during 10-09setting time, it means PID feedback control is abnormal. The treatment is set as 10-10.10 - 09 PID Feedback Signal Fault Treatment Time Factory Setting: 0.0Settings 0.0~3600.0 Sec Unit: 0.1 This parameter is to set the detection time of abnormal PID derivative. If PID deviationdetection time is set to 0.0, the function is disabled.10 - 10 PID Feedback Signal Fault Treatment Factory Setting: 01Settings 00: Warn and RAMP stop01: Warn and COAST stop02: Warn and keep operating This parameter is to set treatment of the abnormal PID deviation.10 - 11 PID Minimum Output Frequency Factory Setting: 01Settings 0: By PID controller1: By AC drive This parameter can decide the source of PID output minimum frequency when AC driveenters PID sleep process. If it is set to 0, minimum output frequency should be set by PID. Ifit is set to 1 and 01-08 is 0, the output frequency is equal to the value of 01-05 setting. If it isset to 1 and 01-08 is not 0, the output frequency is equal to the value of 01-08 setting.5-62DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
