s turn off.
Step 6. Turn the

Lab 3b: Programming the input as a reversing switch.
Step 1. Set P-11 [
CONFIGURABLE
INPUT
] to 1. This programs
the drive to run in the opposite direction when the
configurable input is on.
Step 2. Verify that the
STOP
/
RUN
switch is in the
STOP
position and that the
CONF
IN
switch is in the 0
position.
Step 3. Turn the
STOP
/
RUN
switch to
RUN
, and notice the
direction of motor rotation. Turn the
STOP
/
RUN
switch
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.
