10-15 Integral Value Resets to Zero when Feedback Signal Equals the Target Value
Range
【0】: Disable
【1】: After 1 Sec
【30】: After 30 Sec ( Range:- 1 ~ 30Sec)
10-15=0: As PID feedback value reaches the set point, the integrator will not be reset to 0.
10-15=1~30: As PID feedback value reaches the set point, reset to 0 in 1~30 seconds and inverter
stops. The inverter will run again when the feedback value differs from the set point value.
10-16 Allowable Integration Error Margin (Unit) (1 Unit = 1/8192)
Range
【0 ~ 100】%
10-16=0 ~ 100% unit value: Restart the tolerance after the integrator reset to 0.
10-17 PID Sleep Frequency Level
Range
【0.00~599.00】Hz
10-18 PID Sleep Function Delay Time
Range
【0.0 ~25.5】Sec
10-19 PID Wake up Frequency Level
Range
【0.00 ~ 599.00】Hz
10-20 PID Wake Up Function Delay Time
Range
【0.0 ~ 25.5】Sec
When PID output frequency is less than the sleep threshold frequency and exceeds the time of sleep
delay, the inverter will decelerate to 0 and enters PID sleep mode.
When PID output frequency is larger than the Wake up threshold frequency inverter will enter the PID
mode again as shown in the timing diagram below.

10-22
Min PID Feedback Level.
Range

Example: If 10-21=100 and 10-22=50 and the unit for the range from 0 to 999 will be defined with the
parameters setting of 12-02 , actual feedback value variation range, will be scaled to 50 and 100 only
for display, as Shown below.
