4-2 Function Mode •This signal is also output during DC injection braking. Below is the time chart. Frequency Arrival Signal •This function outputs a signal when the output frequency has reached the set value. For elevating machines, use this signal for applying the brake. 4 Functions •Below is the hysteresis of the frequency arrival signal. ON: (Set frequency - 1% of the maximum frequency) (Hz) OFF: (Set frequency - 2% of the maximum frequency) (Hz) „ 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 (A021 to A035).
Output frequency f on f off Set frequency f on:1% of max. frequency f off:2% of max. frequency (Example) Max. frequency fmax = 120 (Hz) Set frequency fset = 60 (Hz) fon = 120 Ч 0.01 = 1.2(Hz) FA1 foff = 120 Ч 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) 4-54 Output frequency FW RUN Data Symbol Function name Status Description 01 FA1 Constant speed arrival signal ON The Inverter output frequency has reached the F001 set value. OFF The Inverter output frequency has fallen below the F001 set value. 02 FA2 Over set frequency arrival signal ON The Inverter output frequency has exceeded the C042 set value during acceleration.
OFF The Inverter output frequency has fallen below the C042 set value during acceleration. Available input terminals P1-PC, P2-PC, MA-MC (or MB-MC) Required settings C021, C022, C026, C042, C043 Parameter No. Function name Data Default setting Unit C042 Arrival frequency during acceleration 0.0: Does not output arrival signal during acceleration 0.1 to 400.0: Outputs arrival signal during acceleration 0.0 Hz C043 Arrival frequency during deceleration 0.0: Does not output arrival signal during deceleration 0.1 to 400.0: Outputs arrival signal during deceleration 0.0 Hz
