5. Operating the Inverter

 Test Run

The Inverter operates when a frequency (speed) is set.

There are three operating modes for the VS mini:

1. RUN command from the Digital Operator (potentiometer/digital set-

ting)

2. RUN command from the control circuit terminals

3. RUN command from MEMOBUS communications

Prior to shipping, the Inverter is set up to receive the RUN command

and frequency reference from the Operator. Below are instructions for

running the VS mini using the Digital Operator (with potentiometer).

For instructions on operation, refer to page 41.

Operation reference or frequency reference constants can be selected

separately as shown below.
