Pid Fb Status Output - Omron 3G3JX User Manual

4-2 Function Mode
•The disconnection detection signal is output if the frequency reference of the external analog input
remains below the starting frequency for 500 ms.
•The signal stops 500 ms after the frequency reference has exceeded the starting frequency.
•Helps detect disconnection when a frequency reference is issued from the external analog inputs
(FV, FI) with the frequency reference selection set to the terminal (A001 = 01).
•Enabled only when the external analog inputs (FV, FI) are selected.
Example 1: Disabled in multi-step speed operation even when the frequency reference is set to
Example 2: Disabled even when the AT terminal selection is set to the FV/volume selection

PID FB Status Output

When the PID function is used, this function outputs a signal according to the FB value, as illustrated
below.
This is effective as a RUN command in operating multiple pumps.
