Speed Control | Frequency Settings |
Perform the⇒following setup to allow⇒the system to perform Speed control⇒from |
|
the⇒VI/II input terminal: |
|
•Set VI/II Speed Frequency #1,
•Set the VI/II input signal level (VI/II Speed Ref #1) that represents VI/II Speed Frequency #1,
• Set VI/II Speed Frequency Setpoint #2, and
• Set the VI/II input signal level (VI/II Speed Ref #2) that represents VI/II Speed Frequency Setpoint #2.
Once set, as the VI input voltage or the II current changes, the output frequency of the ASD will vary in accordance with the above settings.
This parameter sets VI/II Speed Frequency #1 and is the frequency that is associated with the setting of VI/II Speed Reference Setpoint #1 when operating in the Speed Control mode.
