Sets the responsiveness of PID control when the PID feedback changes quickly.
Sets the function that adjusts the PID output in relation to the frequency reference.
0 : Disabled
1 : Enabled
Sets the PID Trim Mode Lower Limit Value as a percentage of the maximum output frequency.
Sets the first character of the custom unit display when b5-46 = 49 [PID Unit Display Selection =
Custom (B5-68~70)].
Sets the second character of the custom unit display when b5-46 = 49 [PID Unit Display Selection =
Custom (B5-68~70)].
Sets the third character of the custom unit display when b5-46 = 49 [PID Unit Display Selection =
Custom (B5-68~70)].
Note:
• To enable this parameter, you must set b5-71 < b5-38 [PID User Unit Display Scaling]. If you
set b5-71 > b5-38, the drive will disable all PID analog inputs.
• Parameters b5-46 [PID Unit Display Selection], b5-38, and b5-39 [PID User Unit Display
Digits] set the unit, range, and resolution.
Sets the drive to do a 4 to 20 mA wire-break detection on the analog input set for PID feedback.
0 : Disabled
1 : Alarm Only
2 : Fault
3 : Run At b5-83
Sets the speed at which the drive will run if the drive detects a 4 to 20 mA wire-break on the PID
Feedback and b5-82 = 3 [Feedback Loss 4～20mA Detect Sel = Run At b5-83].
Sets the level at which the drive will detect Loss of Prime in the pump.
Note:
• Loss of Prime condition occurs when the measured quantity set by Y1-18 [Prime Loss
Detection Method] decreases to this level for the time set in Y1-20 [Loss of Prime Time] and the
output frequency is at the Y4-02 [Pre-Charge Frequency] level.
• The drive will respond to the Loss of Prime condition as specified by Y1-22 [Loss of Prime
Selection].
• Display unit and scaling are dependent on System Units.
