Determines whether or not a negative PID output reverses the drive rotating direction. setting
b5-10 = 1 mandatory when b5-00 =3 or 4
No. Name Setting Range Default
b5-10 PID Output Reverse Selection 0, 1 0
0 : Reverse Disabled
Negative PID output will be limited to 0 and stop the drive.
1 : Reverse Enabled
The drive will run reversely if PID output is negative.
■ PID Feedback Low /High Detection
By setting b5-11 PID Feedback Low/High Detection, this detects whether the sensor or the
sensor wiring is broken. Always setting b5-11 this function during PID control so as to avoid
machinery accelerating to the maximum frequency and cause by PID feedback low / high.Or
the pump shut down applications cause by feedback overthe detection value
·
PID Feedback Low
This will be detected when the value is lower than the set level for longer than the set time.
·
PID Feedback High
This will be detected when the value is higher than the set level for longer than the set time.
The PID Feedback Low Detection operation is illustrated below. Same way applies to PID
Feedback High Detection.
