Parameter Group 12 - PID "Limits" and "Out of Range" Mode
12-0: : : : Feedback Loss Detection Mode: 0000:Disable
0001:Enable – Drive Continues to Operate After Feedback Loss
0002:Enable – Drive "STOPS" After Feedback Loss
12-0= 0 : Disable; 12-0= 1 : detect to run and display PDER ; 12-0= 2 : detect to stop and display
PDER 。
12-1: : : : Feedback Loss Detection Mode (%): : : : 0 - 100
12-1is the level for signal loss. Deviation = Command value – Feedback value. While the deviation
is larger than the loss level, the feedback signal is lost.
12-2: : : : Feedback Loss Detection Delay Time (s): : : : 0.0 -25.5
12-2 : the action lay time as the feedback signal lost.
12-3: : : : Integrate Limit Value (%): : : : 0 - 109
12-3 : the Limiter to prevent PID saturating.
12-4: : : : Integrator Reset to 0 when Feedback Signal Equals the Intended Value:
0000:Disable
0001:1 second
0030: 30 seconds
12-4=0 : As PID feedback value reaches the command value, the integrator will not be reset to 0.
12-4=1~30 : As PID feedback value reaches the target value, reset to 0 in 1~30 seconds and inverter
stops output. The inverter will output again as the feedback value differs from the target
value.
12-5: : : : Allowable Integration Error Margin (Unit Value) (1 Unit = 1/8192): : : : 0 - 100
12-5=0 ~ 100% unit value : restart the tolerance after the integrator reset to 0.
12-6: : : : PID Feedback Signal: : : : 0000: 0~10V or 0~20mA
12-6 : Feedback signal selection, 12-6=0 : 0~10V
12-7, 12-8: : : : PID Sleep Mode
PID SLEEP MODE:
11-0=1(PID Enable)
5-05=20(PID FEEDBACK Enable)
1-06=PID setting frequency source (Target Value)
12-7 Set the frequency for sleep start, Unit : HZ
12-8 Set the Time for sleep delay, Unit : sec
When PID output frequency is less than the frequency for sleep start and the reaches the time of sleep
delay, the inverter will decelerate to 0 and enter PID sleep mode.
0001: 2~10V or 4~20mA
or 0~ 20mA (si gnal V or I deci de to S W 2)
12-6=1 :
4~20mA
2~10V or
4-51
