In order to determine where control will wait in CYCLE MODE

0505
05, corresponding SCHEDULE
parameter must be programmed to 99. The control will wait on SQUEEZE if SQUEEZE is
programmed to 99, or WELD/COOL if IMPULSES is 99, or HOLD if HOLD is 99.
The following sequence illustrates an example of how to use this CYCLE MODE.
After welding sequence is started with FS3, the control will execute a chain on schedule 00,
wait for re-initiation on schedule 01, execute chain on schedule 02 and then it will weld
indefinitely on schedule 03 (because CYCLE MODE=
0505
0505
05 and IMPULSES=
9999
9999
99). It will continue
to weld until one of two conditions occur: 1) Emergency Stop or Temperature Limit Switch is
open causing sequence to be stopped or 2) FS7 or FS11 is activated causing the control to jump
to schedule 10 or 20, respectively, and execute whatever sequence is programmed there. In this
case for schedule 03, SQUEEZE time must be less than 99 cycles, otherwise the control will
wait on SQUEEZE. In order to wait on HOLD, both SQUEEZE and IMPULSES must not be
programmed to 99.

6.3 SLOPE MODES
The EN1000/EN1001 Series Controls offer UPSLOPE and DOWNSLOPE as standard features
for applications that require their use.
UPSLOPE/DOWNSLOPE function provides a means of gradually increasing or decreasing
weld current. How gradual the increase or decrease occurs is determined by the SLOPE bottom
current and the number of SLOPE cycles programmed in SLOPE COUNT. The number
programmed into SLOPE COUNT will determine the rate at which the control will reach the
programmed weld current. SLOPE COUNT is programmable from 01 to 99 (in ms at 1000 Hz).
When SLOPE MODE is used, its function is to change current gradually. The UPSLOPE mode
causes current to start from a low level and increase for a predetermined number of cycles.
When DOWNSLOPE is in use, the reverse is true. Current will start to decrease to low level for
a predetermined number of cycles.
The number of SLOPE cycles is automatically added to the number of WELD cycles. If 14
cycles of UPSLOPE are programmed in SLOPE COUNT, for SLOPE MODE
0101
0101
01 or
0202
0202
02, and the
number of WELD cycles is 21, the total amount of WELD time is 35 cycles.
