approximately 5 years
Contact DUKANE service for information
on battery replacement
Lower limit is greater than
upper limit
Lower process limit is
greater than Upper process
limit
Improper process limit values
entered
Correct process limit values
Move to Top Of Stroke
before welding
Press head is not at Top of
Stroke
Machine jogged away from Top Of
Stroke position
Move press to Top Of Stroke position by
using the “TOP OF STROKE Position”
screen in setup menu
Process RPM is too high
Programmed spin motor
weld speed is too high
Programmed spin weld speed is
larger than machine capability
Reduce spin motor weld RPM
TOS to trigger distance is
too small
Distance between Top Of
Stroke position and Trigger
position is too small
Trigger position is set too high or
Top Of Stroke position is set too
low
Increase Trigger position value or decrease
Top of Stroke position value
Vertical weld speed is too
high
Programmed press weld
speed is too high
Programmed press weld speed is
larger than machine capability
Reduce press weld speed
Weld duration too short
Weld duration generated by
programmed parameters is
too short
1. Weld Time, Rotations, or
Distance too short
2. Deceleration too low
NOTE: the time for deceleration is
counted as part of the total weld
time or number of rotations
1. Increase Weld Time, Rotations, or
Distance above the “Min.” value
indicated on the Weld Parameters
setup screen
2. Increase spin deceleration
Weld trigger position is
below vertical travel lower
limit.
Cycle will not start since the
programmed press travel is
larger than the set limit
1. Vertical travel lower limit set
too high
2. Trigger position too large
1. Lower vertical travel lower limit, if
possible.
2. Decrease Trigger position
