VI/II Speed Frequency Setpoint #1

 

Factory Default — 0.0

This parameter⇒⇒is used to set the gain and bias of the VI/II input terminal when

Changeable During Run — Yes

the VI/II terminal is used as the control input while operating in the Speed

 

Control mode.

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:

Speed Control

Frequency Settings

Perform thefollowing setup to allowthe system to perform Speed controlfrom

 

theVI/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.
