Two taught poses lie on the axis of a close-fitting guide and have the same tool orientation: one is just outside the guide, and the other is at insertion depth. A joint move reaches both poses accurately, but the shaft brushes the guide between them. The fixture and recorded poses are correctly located. What must change in the insertion command?
Correct answer: A - Use linear TCP motion between the existing poses.
During a dry run, a dispensing nozzle leaves a bead endpoint while the dispense command is still on. The relevant program is shown below. CALL waits for the routine to return; MOVE_COMPLETE waits for arrival. Outputs retain their commanded states until another output assignment, and no other task changes Dispense. Main: CALL ApplyBead MOVE_COMPLETE Park ApplyBead: SET Dispense = ON MOVE_COMPLETE BeadEnd RETURN What does RETURN actually do here?
Correct answer: D - Resume at the Park move without changing Dispense.
A machine has finished its cycle and granted the robot permission to unload. The finished part will fall if the fixture opens before the robot secures it. The open gripper is at the pickup pose, and the fixture is closed. Separate feedback signals confirm a secure grip and a fully open fixture. Select the sequence that transfers the part without losing support.
Correct answer: C - Close the gripper; confirm grip; open the fixture; confirm it is open; withdraw.
An assembly station accepts a bushing when seating depth is 24.8-25.2 mm and all three digital confirmations-base present, insert present, and fixture clamped-are on. A calibrated gauge reads 24.94 mm, and all three confirmations are on. Nominal depth is 25.00 mm. All other process checks have passed. What disposition does this result warrant?
Correct answer: B - Accept the assembly and advance the sequence.
The highest fixture on a pick-and-place transfer is 165 mm above the table. The gripper extends 25 mm below the TCP, and the held part extends another 35 mm below the gripper. The transfer keeps this orientation, and the process requires at least 15 mm clearance between the part and the fixture. All other swept clearances have been verified. What is the lowest permissible TCP height for this transfer?
Correct answer: A - 240 mm
Three production routines reference the same stored approach point P[20]. Only the new large-part routine needs a higher approach; the other two routines and their stored targets must remain unchanged. On this controller, editing P[20] changes every instruction that references it. How should the new approach be entered?
Correct answer: D - Create a separate point and assign it only to the large-part routine.
After an operator selects Work Frame 2 instead of Work Frame 1, all approach and placement points shift by the same amount relative to a fixed fixture. The stored coordinates are unchanged. Reselecting Work Frame 1 restores every point, and no tool or mechanical setup has changed. What should be corrected before the next controlled test?
Correct answer: C - Restore the validated work-frame selection for the routine.
An inductive part sensor changes state when a steel part is inserted and removed. At robot DI[7], qualified checks show 23.6 V with the part present and 0.3 V without it; the corresponding raw input bit follows these changes. DI[8] stays low. The program remains at WAIT PartPresent, and its symbol table assigns PartPresent to DI[8]. All channels are active-high. Where does this evidence locate the fault?
Correct answer: A - PartPresent is assigned to the wrong robot input.
A robot output rated at 0.20 A is proposed for a 24 VDC solenoid coil rated at 7.2 W in continuous operation. The 24 V supply has spare capacity, but the output's channel rating cannot be increased. Treat the coil as a steady DC load. Which current assessment and connection are correct?
Correct answer: B - The coil needs 0.30 A; use a suitably rated inductive-load interface.
The robot's completion output is high from 6 ms to 12 ms after a successful placement. The PLC reads that input only at 0, 20, 40 ms, and so on; there is no pulse-capture hardware. A trace confirms that the pulse reaches the PLC terminal, yet the PLC never records completion. Which interface change removes the underlying timing vulnerability?
Correct answer: C - Hold completion high until the PLC acknowledges it.
