How can resolve problem PID warning in delta MS300 drive ?
PID feedback error (PID)
PID feedback loss (warning for analog feedback signal; works only when PID enables)
When the analog input is lower than 4 mA (only detects analog input 4–20 mA)
Warning” occurs when Pr.08-09=0 or 3. The “Warning” automatically
clears when the feedback signal is larger than 4 mA.
“Error” occurs when Pr.08-09=1 or 2. You must reset manually.
Warning setting parameter
Pr.08-09
0: Warn and continue operation
1: Fault and ramp to stop
