How can resolve PID warning in delta C2000 series drive ?
PID feedback error (PID)
PID feedback loss (warning for analog feedback signal; works only when PID enables)
Action condition - When the analog input is lower than 4 mA (only detects analog input of 4–20 mA)
Warning setting parameter
Pr.08-09
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: Warn and operate at last frequency
“Warning” occurs when Pr.08-09 = 0 or 3. The “Warning” automatically
clears when the feedback signal is larger than 4 mA
Tighten the terminals again.
Replace with a new cable
