3.6 Local-control Test
CAUTION
MOTOR START!
Ensure that the motor, system, and any attached
equipment is ready for start. It is the responsibility of the
user to ensure safe operation under any operational
condition. Failure to ensure that the motor, system, and
any attached equipment is ready for start could result in
personal injury or equipment damage.
NOTE
The hand on key on the LCP provides a local start
command to the frequency converter. The OFF key
provides the stop function.
When operating in local mode, the up and down arrows
on the LCP increase and decrease the speed output of the
frequency converter. The left and right arrow keys move
the display cursor in the numeric display.
1.
Press [Hand ON].
