Functions
External Analog Input Disconnection Detection
• Outputs a signal if an error is detected in the external analog inputs (FV, FI).
• 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
the external analog input (A001 = 01).
Example 2: Disabled even when the FV/FI selection is set to the FV/VR selection (A005 = 02) or
FI/VR selection (A005 = 03) since the frequency reference is set on the Digital Op-
erator (volume) with the AT terminal turned on.
