CONTREX M-Traverse - Manual (Page 71)

3 - 24
The Resume Enable parameter allows you to specify the conditions under which you
resume operation.
Resume Enable (CP-32)
If you interrupt the operation (F-Stop), the Resume Enable (CP-32)
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.
Both the Follower and the Lead information is saved at power-down. If
there has been no change in the mechanical position at power-down,
then the profile can be resumed at power-up.
If the mechanical position has changed and you resume operation, the
Follower could make an abrupt shift to resolve the position error. This
can severely injure you or damage the equipment. The specific conse-
quences of this abrupt shift can vary, depending on your use of the
equipment and your system's design. Install safety equipment that is
appropriate for your application.
The factory default for the Resume Enable Control Parameter is found in Table 3-16.
To modify the default parameter refer to Table 3-17. If you are uncertain how to enter a
Control Parameter, review the
Operations: Keypad section.
DANGER
When you resume operation
the Follower could make an
abrupt shift.

damage equipment.

appropriate for your application.
