6. TROUBLESHOOTING GUIDE
The chart that follows contains the most frequently encountered issues.
SYMPTOM CAUSE or REMEDY
No power indication when • Check main power supply for proper voltage.
‘POWER ON’ button is pressed
• Check supply fuses and circuit breakers.
• Verify that the main disconnect switch is on.
• Verify that the E-Stop is not engaged (E-Stop Loop closed.)
• Check bulb in ‘POWER ON’ push button.
No display on power up • Check cabling connection between display and servo drive.
• Check 5 Volt logic supply LED on motion control card on right side
of Servo Drive/Amplifier under orange connectors.
• Check fuses in drive under right side cover.
Feed will not jog • Check that the Feed is in manual mode. Move selector switch to ‘AUTO’;
press the ‘POWER ON’ push button to reset control.
• Check if the Feed is in ‘SET-UP’ mode. Waiting for press.
• Check if ‘IN POSITION’ indicator is off. Check parameters. Check drive
for Error Codes.
• Check ‘FAULT’ in display. i.e. ‘SERVO AMP FAULT’. Check drive for Error
Code. See Section 6.1
‘POWER ON’ indicator is lit, • Check that the ‘IN POSITION’ indicator is lit. If not, check parameters.
Feed will not operate.
• Check that the Error message is in the Display. If so, check error
description in Section 6.1
• Move selector switch to Auto, press ‘POWER ON’ button (E-Stop will show
in display), release ‘POWER ON’ button, try to jog feeder.
Feed will not accept new feed • Check that the Selector switch is in Set-Up mode (running Set-Up program).
length or other parameters
• Check that the Selector switch is in Auto mode and ‘CYCLE START’ has
been pressed (running Auto Program). Press ‘POWER ON’ push button
to reset.
• Check that the Run/Program toggle switch is in ‘RUN’ position; this will only
allow length, speed, and count to be changed. Set the Program Position;
then the Program position will allow any parameter to be changed.
Inaccurate feeding • Adjust rolls for correct material thickness; roll release lever must have
small amount of play/wobble in it.
• Adjust spring pressure (Do not bottom springs. Catastrophic damage
can occur.)
• Confirm if rolls are slipping on strip. Remove oil from feed rolls, reduce
acceleration, check tool for binding/slugs, etc.
• Adjust Upstream Equipment if Upstream equipment not providing
adequate/consistent free loop.
• Check roll release for proper settings.
Feed runs backwards • Check for negative feed length, i.e. minus sign in length (–5.125).
• Verify that direction parameter has been reset. Check CW or CCW
direction parameter.
Servo Amp Fault This is a generic display prompt indicating a fault on the Servo Amplifier.
• Look at the diagnostic display on the Servo Amplifier. The cause of the
fault can be determined by reading the Error Code.
• Refer to Sections 6.1 and 6.2. This fault condition can be caused by any
one of the errors in the lists.
• Check for Error Code first, then reset the Servo Amplifier by turning the
power off, waiting 10 seconds, then powering back on.
• Verify that the fault will not reset. Call the factory for assistance.
