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
0001: 2~10V or
4~20mA
12-6
:
Feedback signal selection, 12-6=0
:
0~10V
or 0~ 20mA (si gnal V or I deci de to SW2)
12-6=1
:
2~10V or
4~20mA
(si gnal V or I de ci de t o SW2)

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.
