“Inboard ram test failure”
Problem:
Something is wrong with the SmartPAC 2 main processor board. The board may
need to be serviced or replaced.
Remedy:
Try turning the power off, then on again. (You cannot use the RESET key to reset
this error.) If the message continues to appear, contact Wintriss Tech. Support for
assistance or replacement of the board.
“Resolver signals incorrect” or “Resolver drive signal incorrect”
Problem:
There is a problem with the resolver assembly.
Remedy:
Check to make sure that the Master/Slave jumper, JP101, on the SmartPAC 2
board (see Figure 2-25, page 2-51) is set to the following position:
•
MASTER for a SmartPAC 2
without
WPC Clutch/Brake control
integration
•
SLAVE for a SmartPAC 2
with
WPC Clutch/Brake control integration
Check the resolver and wiring. Make sure that the terminals are tightened on bare
wire and not on insulation (see
Connecting the Resolver Wiring
necessary, contact Wintriss Tech. Support for assistance or replacement of the
resolver.
“Stop time exceeded”
Problem:
The stopping time of the press has exceeded the limit set in SmartPAC 2
Initialization. You should have been pre-warned of this condition by the brake
warning LED, which flashes whenever the stopping time is within 10 milliseconds
of the stop-time limit.
This message displays when the stop-time limit is not sufficient to allow for
normal brake wear, or the brake is excessively worn and needs servicing. If the
brake is worn, a dangerous safety problem may exist and should be corrected
immediately.
Remedy:
First, perform several 90
°
stop-time test runs to get an actual reading for your
press’s stop time. Compare these results with the results you got the last time you
performed the test. Decide if the current stop-time limit is realistic or needs to be
changed slightly. See page 4-31 to calculate the correct stop-time limit and
page 6-22 to perform the 90
°
stop-time test. If you change the limit, you may have
to relocate your light curtains and/or two-hand controls. Refer to the appropriate
manual for assistance.
If the brake is worn, you should have your maintenance personnel service the
brake immediately.
