Functions
Constant Speed Arrival Output (01: FA1)
•Outputs a signal when the output frequency has reached the level set in the frequency setting
(F001, A020, and A220) or multi-step speed reference (A021 to A035).
Output Over Set Frequency (02: FA2)
•Outputs a signal when the output frequency has exceeded the arrival frequencies during
acceleration/deceleration set in [C042, C043 (FA2)].
Alarm Output
This is output when the Inverter trips. If you use the relay for alarm outputs, set and check
operation,, as the SPDT contact is used for the terminals. For details, refer to the description of the
relay output, "Multi-function Output Terminal ON Delay/OFF Delay" (page 4-60).

(Example)(Max. frequency fmax = 120 (Hz)
Set frequency fset = 60 (Hz)
foff = 120×0.02 = 2.4 (Hz)
During acceleration:ON at 60 - 1.2 = 58.8 (Hz)
During deceleration:OFF at 60 - 2.4 = 57.6 (Hz)
