MDS-1055 UNIVERSAL LIMIT KIT
The MDS-1055 Universal Limit Kit is an accessory that installs between the Master Drive Unit and any of the
three control modules: the *MDS-1002 Straightline, the MDS-1003 Stitch and the MDS-1005 Weaver Control
Module. This limit kit adds the ability to CYCLE between limits, STOP AT LIMIT, or RAPID RETURN. All exist-
ing functions of the control modules are maintained.
CYCLE MODES:
a) CYCLE - Cycles between two limits. Limit contact does not turn off the weld contactor.
b) STOP AT LIMIT - Limit contact in the direction of travel set by the control module Carriage Travel
Switch will stop motion and turn off the weld contactor. The Carriage Travel Switch will reverse
the travel direction and start motion away from the contacted limit. The weld contactor will not
automatically turn back on when the machine exits a limit.
c) RAPID RETURN - The machine will run at the preset welding speed in the direction set by the
Carriage Travel Switch on the control module until it hits a limit. When this limit is hit, the machine
will turn off the weld contactor, reverse direction, and travel at full speed to the opposite limit. Upon
reaching the limit, the machine stops.
