CP-32 RESUME ENABLE
If you interrupt the operation (F-Stop), the Resume Enable parameter allows you to keep track of
error in both the Follower and Lead positions. It also allows you to freeze the Lead position and
keep track of error in the Follower position. The M-Traverse will adjust for the error when you
resume operation.
Resume is disabled by entering "1" in CP-32.
To keep track of error in both the Follower and Lead positions enter "2" in CP-32.
To freeze the Lead position and keep track of error in the Follower position, enter “3” in CP-32.
When you resume operation, the Follower could make an abrupt shift back to its former position,
which can severely injure you or damage equipment. The specific consequences can vary,
depending on your use of the equipment and your system's design. Install safety equipment that
is appropriate for your application.
CP-35 HOME SYNC POLARITY
The Home Sync Polarity (CP-35) parameter allows you to choose between rising edge polarity
(positive going signal) or falling edge polarity (negative going signal) during "Home Seek". This
feature is extremely useful when you use reflective or transmissive optical sensors for the Home
sensor. Enter "1" in CP-35 for a rising edge, or "2" for a falling edge. Refer to the diagram
below.

CP-36 FORWARD/REVERSE LIMIT POLARITY
The Forward/Reverse Polarity Limit (CP-36) parameter allows you to choose between rising
edge polarity (positive going signal) or falling edge polarity (negative going signal) so that the
Follower mechanism will not travel beyond the traverse length limit. This feature is extremely
useful when you use reflective or transmissive optical sensors for the Home sensor. Enter "1" in
CP-35 for a rising edge, or "2" for a falling edge.
