Installation, Maintenance, Service & Part List Manual
swap an old compact flash over into a new computer module. You may transfer faults over or there may be
compatibility issues.
In general, the computer module is best diagnosed by eliminating all other possible alternatives. The
following table lists some symptoms and diagnostics that may be used to determine if the problem is due to
the computer module, and thus should be replaced.
Symptoms Diagnostics
Any sympton Verify that the 5VDC is within ±0.25 volts DC at the overlay
connector.
Verify that the 12VDC is ±1 volts DC.
Verify that the -12VDC is ±1 volts DC.
Verify that the 24VDC is ±2 volts DC.
Verify that the 115VAC is ±5 volts AC.
Use service code 521 to test the I/O of each port.
X, Y or Z-axis Faulting Use service code 131 and LEDs on the computer module to test the
encoder portion of the axis.
Swap the axis port cable and power cable with a different axis to
see if the problem follows the motor/servo or the computer module.
Spindle Faulting Use service code 510 to test the spindle encoder.
Use service code 521 to test the digital I/O from the computer
module to the AC Drive.
Handwheel will not work Use service code 132 to test the encoder portion of the handwheel.
Digital Input Errors Make sure the LEDs to the corresponding digital input turn OFF and
ON as expected.
Use service code 521 to test all the inputs to the computer module.
Digital Output Errors
Make sure that the LED corresponding to the output function turns
OFF and ON using service code 521. Note outputs require the NC
Ready function to be activated and E-stop to be in the out position.
E-stop error cannot be cleared.
Use Service code 521 to verify that the E-stop signal is not being
seen by the computer module. Verify E-stop LED turns ON.
Critical Keys (ON, OFF, GO, STOP
& AUX) are not responding.
Check LED’s above overlay power connector when buttons are
pressed. Light should only be on when the button is being held
down.
Verify that the 24VDC (at overlay connector) is between 22-26 volts
DC.
Use Service code 521 to identify which critical keys are working.
Blank Video or Distorted Video Verify that the 12VDC on the Overlay Power connector is between
11-13 volts DC.
A standard desktop monitor with a VGA port may be connected to
verify if any signal is being sent out from the computer module.
Overlay Keys not responding Note that when an overlay key is not responding to a command but
a beep is produced by the pendant this is an indication that the
COM port on the computer module is functioning correctly.
Verify that the Overlay software is running by using an external USB
keyboard and pressing “Ctrl-Alt-Delete” this will bring up a window
