External Analog Input Disconnection Detection
•Outputs a signal if an error is detected in the external analog inputs (O, OI).
•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
(O, OI) with the frequency reference selection set to the terminal (A001 = 01).
•Enabled only when the external analog inputs (O, OI) are selected.
Example 1: Disabled in multi-step speed operation even when the frequency reference is set to
the external analog input (A001 = 01).
Example 2: Disabled even when the AT terminal selection is set to the O/volume selection
(A005 = 02) or OI/volume selection (A005 = 03) since the frequency reference is set
on the Digital Operator (volume) with the AT terminal turned on.
Network Error
This function detects and outputs a network error during RS485 ModBus communication.
•The error is output during RS485 ModBus communication if the next signal does not come even
after the specified time period in C077.
