VI/II Freq #1
This parameter is used to set the gain and bias of the VI/II input terminal when
the VI/II terminal is used as the control input while operating in the Speed
Control mode.
Note: See note on
for further information on the VI/II
terminal.
VI/II Input Speed Control Setup
Perform the following setup to allow the system to receive Speed control input
at the VI/II input terminal:
• Program

• Provide a Run command (F and/or R).
Speed Control
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
, and
• Set the VI/II input signal level (VI/II Speed Ref #2) that represents
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
Speed Control mode.
