Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
This inverter can be configured to output a control signal from the multi-function output terminal if the
PID feedback value falls out of the setting range.
Allocate the Multi-function Output 11/12 Selection (C021/C022) or the Multi-function Relay Output (AL1,
AL2) Function Selection (C026) to 31 (FBV).
Set the Feedback Comparison Signal Off/On Level (C052/C053) in units of percentage as 100% of the
1st/2nd Maximum Frequency (A004/A204).
When the RUN command is input by the PID function, the FBV output starts with the ON state, indepen-
dent of the Off/On level of the feedback comparison signal.

Use this parameter to monitor the PID feedback value in units of percentage as 100% of the maximum
frequency.
The monitor value is displayed as a product of the feedback value and the PID Scale (A075).
d004 = Feedback value  PID Scale (A075)
Use this function to clear the integral value of PID operation.
Allocate the Multi-function Input 1 to 7 Selection (C001 to C007) to 24 (PIDC). The
integral value is cleared every time the PIDC terminal is turned ON.
Never turn ON the PIDC terminal during PID operation. Doing so may cause an overcurrent trip. Be
sure to deactivate the PID operation before you turn ON the PIDC terminal.
This inverter can be configured to shut off its output when the PID Sleep Operation Delay Time (A157)
elapsed since the PID output reached the PID Sleep Operation Level (A156) or lower. The stop method
(deceleration stop/free-run stop) depends on the Stop Selection (b091) setting. The PID sleep function
will not be activated if the normal PID output is restored within the PID Sleep Operation Delay Time.
Even if the PID disabled signal is input by the PID function, the inverter will shut off its output when the
time set in A157 elapsed since the frequency reference value reached the level set in A156 or lower.
The stop method depends on the b091 setting.
