When the Arc is in the off condition the Registers will display the statistical
average for the last weld.
Registers 7-9: Contains the BCD coded Time and Date at the start of the last
weld. These registers will only update when a new weld is detected or a weld
summary is loaded from memory. The Time and Date parameters are in BCD
format. The low nibble is the 1’s units and the upper nibble is the 10’s units.
Note: When setting the Real time Date and Time the values loaded into the
Registers 7-9 must be in a BCD format.
Register 10–14: Used to indicate the statistical mean values as calculated
during the Learn Mode for each weld within the learned part. The value is an
integer value and represents mean value that is used with the sigma value to set
the upper and lower control limits for parameter testing. These values have the
same scaling as Register 2-6 (see above table).
Register 15: Spare Register - Not used at this time.
Register 16: The current weld count since the last weld count reset. This
counter is incremented when the total arc time for a weld is greater then 0.5
seconds. This prevents false arc starts from being counted as a valid weld.
Register 17: Indicates the number of weld summaries stored in the weld
memory. The maximum number of welds stored is 1024. Writing a new value to
this register will cause the next collected weld to be written to that weld number
location. The Welds will only be saved if the Save Weld summary coil (2) has
been set and the minimum weld time is greater than 0.5 seconds.
Register 18: This register sets the number of raw data points to be averaged to
generate a single sampled value. The minimum value is 1 and the maximum
value is 255. Setting this value to 0 will disable the Analog Data collection
routines.
Register 19: This register is used to read a previously stored weld summary
from memory. Set the desired weld summary number in this register then set the
Read Weld Memory Coil 7. The value will be written to Register 2 – 12.
Maximum value is 1024.
Register 20-21: These registers are used to specify the conditions required to
establish an arc on signal. To set the auto arc on signal the Voltage and current
sensor values must exceed both values stored in the these registers. If any
single sensor input drops below this level the arc on signal will be reset.
Register 22-26: These registers are used to specify the process control limits
used for in process monitoring. The MSB and LSB bytes are used as
independent byte size variables and have a Byte size decimal range of 0-255.
