Functions
82
LINEAR STEPPER #nn ASSIGNED (0 = OFF)
83
SUREWELD STEPPER #nn ASSIGNED (0 = OFF)
(nn = 1-99)
Function #82 assigns a linear stepper to a weld schedule. Function
#83 assigns a SureWeld stepper to a weld schedule.
The MedWeld 4000 can have up to 99 independent linear steppers,
and up to 99 SureWeld steppers. Linear steppers have 5
programmable levels (called “steps”) to provide additional energy.
When either function appears in a weld schedule, the appropriate
stepper is advanced (incremented) each time you execute the weld
schedule.
If it is used in a weld schedule, either function MUST be the
first
function in the schedule.
Valid stepper numbers are 1 – 99. To disable a stepper for a
schedule, assign the stepper as zero (#0). For more details about
steppers, refer to Chapter 6, "Stepper Data".
86
TIP DRESS ADVANCE GROUP #nn STEP #m
(nn = 1-99 m = 1-5)
This function advances all the steppers assigned to the group
number programmed in this function, to the step number specified
in the function.
Suppose this function reads: TIP DRESS ADVANCE GROUP #02
STEP #05. Every stepper (1 – 99) assigned to group #02 would
advance to Step #5.
NOTES:
This function can advance several steppers simultaneously. For example,
your application may use several different weld schedules to execute a
weld on the same tool, but those schedules may be assigned to different
steppers (to account for weld variations).
This function allows you to advance every stepper assigned to a group
each time any schedule finishes a weld. (Every time the electrodes weld,
EVERY
stepper involved is also advanced.)
Program the group assignments using the Stepper Display provided from
the DEP-100S. For more information, see “Linear Steppers” on page 6-
1.
09
STEPPER MACH=nn PART=nn (0=OFF)
This function allows the user to assign two steppers to a schedule.
The stepper additional currents are added together. One stepper is
used as a machine stepper to adjust the heat for the machine. The
other stepper is a part stepper and used to adjust the heat on an
individual part. The part stepper can be reset by inserting Function
#10 (below) in a separate schedule and executing the schedule after
the part is complete.
