ERROR 0403 Robot failed position verify
Errors 400, 401, 402 and 403 indicate that an axis failed its Position Verify
test. The Position Verify test monitors axis movements. If the axis moves
to its home position in too few or too many steps, the test fails.
PROBABLE CAUSE:
• The belt is slipping, due to incorrect tension, a loose motor pulley
or a loose belt clamp. This can also be caused by a bad motor
drive circuit.
Displayed Error
ERROR 0500 Saturation error
Error 500 indicates an empty filter location on the filter wheel, or that the
filter wheel is not installed.
PROBABLE CAUSE:
• All wavelength locations must have either a bandpass or a filter
blank installed, or this error will occur. If the entire wheel is not
installed, the reader will also display this error.
