Inovance MD500-PLUS Series - Setting the Main Frequency through Ais

Function Application
‑503‑
Note
Distinguish this parameter from F0‑23 (Retentive memory of digital setting frequency upon
stop). F0‑23 determines whether the frequency setting is retained or cleared after the AC
drive stops. F0‑23 is related only to the stop state of the AC drive, rather than power failure.

3.1.2.4 Setting the Main Frequency Through AIs
The main frequency can be set by using three analog input (AI) terminals: AI1, AI2, and
AI3. If F0‑03 is set to 2, AI1 is used to set the main frequency. If F0‑03 is set to 3, AI2 is
used to set the main frequency. If F0‑03 is set to 4, AI3 is used to set the main
frequency.
As a frequency source, each AI terminal supports five types of AI curves. The AI curve
is used to define the relationship between the analog input voltage (or current) and
the corresponding settings.
