Lab 3b: Programming the input as a reversing switch.

Step 1. Set P-11 [

] to 1. This programs

the drive to run in the opposite direction when the
configurable input is on.

/

RUN

switch is in the

STOP

position and that the

CONF

IN

switch is in the 0

position.

Step 3. Turn the

STOP

/

direction of motor rotation. Turn the

STOP

/

RUN

to

STOP

to stop the drive.

Step 4. Turn the

CONF

IN

switch to 1, and notice that the

direction of motor rotation is reversed. Turn the

CONF

IN

switch to 0 to stop the drive.

Important: If you set the

STOP

/

RUN

SWITCH

to

RUN

while the

CONF

IN

switch is set to 1, or vice versa, a drive

fault will occur and CF will be displayed. The
drive stops if more than one input (forward,
reverse, or jog) is on.
