        Overview Manuals Pulse Modes Count Events PLC Data Path Product Applications

        Features:

        • Hardware pulse capture: Counter channels follow field pulses beyond the normal cyclic-input task.
        • Pulse-source flexibility: The input can be configured for the installed encoder or directional pulse arrangement.
        • Defined coincidence event: A reached count can be exposed to the controller and a qualified external receiver.
        QD62E belongs in a MELSEC-Q position where a machine needs a count or position event from a pulse source, rather than a simple on/off indication.

        Its count value, status and commands pass through assigned I/O signals and buffer memory, making the module configuration part of the PLC application.

        QD62E supplies count state and comparison results; the controller program and connected equipment determine the machine action that follows.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • One-phase input: A single pulse stream supports accumulation where direction is supplied elsewhere or not required.
        • Two-phase input: A/B pulses allow direction-sensitive counting when the encoder and wiring preserve their phase relationship.
        • CW/CCW input: Separate directional pulse streams can be assigned to forward and reverse movement.
        • Speed selection: The channel range is chosen for the actual pulse source, not copied from an unrelated encoder.
        • Present count: The hardware counter maintains the running value used by the application.
        • Coincidence comparison: A configured count point can produce a comparison result without waiting for the CPU scan.
        • External event: The source-type transistor output carries the qualified coincidence result to a receiving circuit.
        • Preset function: An external signal or program command can establish the count reference for the next cycle.
        • I/O assignment: The MELSEC-Q project reserves the module position and its control/status signals.
        • Buffer memory: Count values and function settings are exchanged with the CPU through module data areas.
        • Program interpretation: The sequence must use the intended channel and comparison state rather than a similarly named tag.
        • Counter state: Application logic should distinguish a valid running value from a counter error or stopped count.
        • Encoder position tracking: Counts quadrature pulses for machine position or travel evidence.
        • Length measurement: Converts roller or wheel pulses into material movement.
        • Batch counting: Accumulates fast product or index events beyond normal scan timing.
        • Speed monitoring: Uses pulse frequency to supervise rotating or linear equipment.
        Description
        QD62E receives encoder or pulse-train signals through two dedicated counter channels in a MELSEC-Q rack. The CPU can use the resulting count without having to detect every edge in its ordinary scan.

        On an indexing or length-control machine, QD62E ties a response to measured travel rather than elapsed time. This lets the controls engineer work from an actual position event instead of an approximate delay.

        The installed use of QD62E is defined by more than the card itself: pulse form, counter mode and the chosen event point belong to the controller project. A replacement must inherit that context to behave like the original machine.
        Alternative Names
        QD-62E QD 62E
        Technical notes
        QD62E uses a 40-pin field interface, while Mitsubishi lists the applicable A6CON-series mating connectors as separate accessories. A module-only spare may therefore arrive without the part needed to reconnect the installed cable. Before a planned change, identify the actual connector variant and pin assignment; stop if the field conductors cannot be transferred under an approved wiring plan.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        QD62E counts correctly at jog speed but loses position in production. Which evidence should be captured?
        Capture the input waveform at operating speed, the selected counter-speed range and any noise near the cable. Slow tests cannot expose bandwidth or interference problems.
        Before restarting an indexed axis with a replacement QD62E, the count direction is reversed. Should the PLC calculation be inverted?
        No. Restore the original encoder phase order and selected count mode first. A calculation change can hide reversed field direction while leaving preset and comparison behavior wrong.
        A machine builder changes an encoder to a different supply level while retaining QD62E. Can the previous input circuit simply be reused?
        Only if the QD62E physical input wiring and terminals are rated and connected for the new encoder voltage and pulse form. Reconcile the common and applicable OEM connection diagram before energizing the revised circuit.
        Purchasing finds a QD62 for a failed QD62E. Can the family similarity justify substitution?
        No. QD62E uses a source-type coincidence transistor output, whereas QD62 uses a sink-type output. Stop the substitution unless the receiving circuit, input conditions and PLC configuration are engineered for the other variant.
        A replacement QD62E counts pulses, but the machine triggers before the intended position. What should controls staff compare?
        Compare the active coincidence setting, count direction and application response with the archived cycle. A correct running count does not prove the event threshold is the one the machine used before the change.
        Near the end of a long QD62E production run, the count reaches its configured limit. Is an automatic wrap always expected?
        No. A linear counter reports overflow and stops counting when its counting range is exceeded. Only ring-counter mode cycles between the preset lower and upper limits without an overflow error. Identify the selected mode before interpreting the apparent jump as pulse loss.
