Infinity™ Series Servo Ultrasonic Press Systems QUICK START GUIDE
Explanation
Servo press has reached the defined maxi-
mum travel limit.
Communication between the servo control-
ler and the motherboard has been compro-
mised.
The press is unable to reach the Top-of-
Stroke position.
The press system senses an excessive
amount of force when idle.
The press position deviated excessively
from the defined Top-of-Stroke position
when idle.
The press system detected a problem with
the linear position encoder.
The servo controller experienced a
termporary over voltage condition likely due
excessive deceleration. The braking shunt
hardware may be damaged.
An implausible comination of the ESTOP
inputs was detected.
The servo controller temperature is below
safe operating conditions.
An implausible motor hall sensor transition
was detected.
The press system detected a problem with
the linear position encoder tested against
motor hall sensors.
An implausible combination of the Operate
Switch 1 inputs was detected.
An implausible combination of the Operate
Switch 2 inputs was detected.
The press system detected a problem with
the transducer door wiring.
Check door switch and wiring.
Operate Switch 2 Pressed before Cycle
Start
Auto In Switch closed at End of Cycle
Generator or Press Not Ready
Weld Limits enabled for continuous oper-
ation
Solution
Increase the maximum travel limit position.
Adjust weld parameters to reduce the distance traveled
during the weld and hold.
Contact Dukane.
remove obstruction detected at Top of Stroke.
Adjust Top of Stroke position to be defined higher than
obstruction.
This alarm can occur when an ultrasonic stack is
removed from the press when power is on. Be sure
to turn system power off when disassembling and
reassembling the stack.
If alarm appears when not changing stacks, contact
Dukane.
Contact Dukane.
Contact Dukane.
Most likely too aggressive deceleration settings. Possible
failure of the braking shunt or power supply.
The NO and NC E-STOP inputs remained at the same
logic level for too long. Must cycle power on the
thruster.
Possible failure of servo controller.
Check servo motor feedback wiring.
Check servo motor feedback wiring.
Check Operate Switch 2 wiring.
Check Operate Switch 1 wiring.
release Switch 1 before pressing both activation
switches to start a cycle.
Verify wiring of both switches.
release Switch 2 before pressing both activation
switches to start a cycle.
Verify wiring of both operating switches.
remove active Auto-In signal.
Verify wiring to Auto-In signal.
Wait for initialization process to complete.
Cycle power on IQ generator.
If alarm persists, contact Dukane.
Change Weld Mode from Automation.
Disable Weld Method.
