Analog input current loss (including all analog 4–20mA signals)
When the analog input (Pr. G2-41 = 2) is lower than 3.6 mA (only detects analog
input 4–20 mA)
The action condition is attained for 0.1s
Fault Treatment Parameter
Pr. G2-49
AI3 signal loss action:
0: Disable
1: Warning & continue OPER
2: Fault & Ramp to Stop
3: Fault & Auto-Decel
4: Fault & Coast to Stop
5: Fault & by Quick Stop Time
6: Warning & FREQ Lower Limit OPER
It is “Warning” when Pr. G2-49 = 1, and the warning will be automatically
cleared when the analog input signal is ≥ 4 mA.
It is "Fault” when Pr. G6-49 = 2–5, which must be reset manually.
It is “Fault” when Pr. G2-49 = 2–5 and will be recorded.
Loose or broken AI3 wiring
Tighten the terminals again.
Replace with a new cable.
If the ACE error still occurs after checking all the wiring, return to the factory for
repair.
