(a) Alert output
The QD73A1 compares accumulated pulses that are output during the positioning with alert output
accumulated pulses. If accumulated pulses exceed the amount of the alert output accumulated pulses, the
error "Accumulated pulse alert" (error code: 130) occurs. (Even after the error occurs, the positioning
continues.)
(b) Immediate stop processing
The QD73A1 compares accumulated pulses that are output during the positioning with immediate stop
accumulated pulses. If accumulated pulses exceed the amount of the immediate stop accumulated pulses, the
QD73A1 performs the following processing and stops the positioning.
Excessive error signal (X17): ON
Accumulated pulse: Clear to 0
Servo ON signal (SVON): OFF
BUSY signal (X14): OFF (Positioning complete signal (X15) does not turn on.)
Turn on PLC READY signal (Y2D) to restore the positioning (In the same way as when an excessive error
occurs).
(2) Executing procedure
The following is the executing procedure of the accumulated pulse error detection function.
Start
End
Measure the reference value.
Execute the positioning.
Save the measured reference value in the flash
ROM inside the QD73A1.
Set the data to use the accumulated pulse error
detection function.
