TECO N310 Series - Feedback Loss Detection Level; Feedback Loss Detection Mode; Integration Limit Value

Chapter 4 Software Index
4-49
09-08: Feedback Loss Detection Mode 0:Disable
1:Enable – Drive Continues to Operate After Feedback Loss
2:Enable – Drive “STOPS” After Feedback Loss
09-08= 0: Disable, 09-08= 1: detect, continue running, and display ‘PDER’, 09-08= 2: detect, stop,
and display ‘PDER’.
09-09: Feedback Loss Detection Level (%) 0 - 100
09-09 is the level for signal loss. Error = (Set point – Feedback value). When the error is larger than
the loss level setting, the feedback signal is considered lost.
09-10: Feedback Loss Detection Delay Time (s) 0.0 -25.5
09-10: the minimum time to consider the feedback signal lost.
09-11: Integration Limit Value (%) 0 - 109
09-11: the Limiter to prevent the PID from saturating.
09-12: Integration Value Resets to Zero when Feedback Signal Equals the Intended Value
0:Disable
1:1 second
30: 30 seconds
09-12=0: As PID feedback value reaches the set point, the integrator will not be reset to 0.
09-12=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.
09-13: Allowable Integration Error Margin (Unit) (1 Unit = 1/8192) =0 ～ 100
09-13=0 ~ 100% unit value: Restart the tolerance after the integrator reset to 0.
09-14: Sleep Frequency Level（Hz） = 0.00 ~ 400.00
09-15: Sleep Function Delay Time（S）= 0.0 ~ 25.5
09-16: Wake up frequency Level（Hz） = 0.00 ~ 400.00
09-17: Wake up function Delay Time（S）= 0.0 ~ 25.5
PID SLEEP MODE:
09-00=1(PID Enable)
02-06=0(PID FEEDBACK Enable)
00-05=PID setting frequency source (Target Value)
09-14: set the sleep threshold frequency, Unit: HZ
09-15: set the time for sleep delay, Unit: sec
09-16: set the wake threshold frequency, Unit: HZ
09-17: set the time for wake delay, Unit: 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 enter PID sleep mode.
When PID output frequency is larger than the Wake threshold frequency for Wake start the inverter will
reactivate and enter PID wake mode. The time diagram is as follow:
