[DESIGN PRECAUTIONS]

WARNING

Do not write data to "read-only area" or "reserved area" in the buffer memory of the intelligent function module. Also do not turn ON/OFF the "reserved" signal in I/O signals to the programmable controller CPU. Doing any of these operations may cause a malfunction of the programmable controller system.

When a transistor for external output fails, the output may be ON or OFF status. Create a circuit for monitoring output signal that may lead to serious accident.

CAUTION

Do not install the control lines and/or pulse input wiring together with the main circuit or power lines, and also do not bring them close to each other. Keep a distance of 150mm (5.91 inch) or more between them. Failure to do so may cause a malfunction due to noise.

[INSTALLATION PRECAUTIONS]

CAUTION

Use the programmable controller in the environment conditions given in the general specifications of the User's Manual for the CPU module. Failure to do so may cause an electric shock, fire, malfunction, or damage to or deterioration of the product.

TROUBLESHOOTING

OVERVIEW

1.1 Features

This section describes the features of the QD64D2.

(1) Counting at the maximum counting speed of 4Mpps is possible. (In 4

multiples of 2 phases)

Since the QD64D2 can be used for high-resolution encoder (e.g. linear scale), the equipment can improve position detection accuracy and a workpiece can be moved at high-speed.

(2) Wide range of expression on counting (from -2147483648 to 2147483647)

Count values can be stored in 32-bit signed binary.

(3) Pulse input selection

Pulse input can be selected from 1 multiple of 1 phase, 2 multiples of 1 phase, 1 multiple of 2 phases, 2 multiples of 2 phases, 4 multiples of 2 phases, and CW/CCW.

(4) Counter format selection

Either of the following counter formats can be selected.

(a) Linear counter format

From -2147483648 to 2147483647 can be counted and an overflow can be detected when the count range is overrun.

(b) Ring counter format

Counts are repeatedly executed between the ring counter upper limit value and ring counter lower limit value.

(5) Coincidence detection

The QD64D2 can compare the present value and comparison point, notify the comparison result with input signal, and start an interrupt program when they match. It also mounts 2-point external coincidence output for each channel, which permits controlling external devices at high-speed.

According to application, select the coincidence output function or continuous comparison function.

(a) Coincidence output function

Set 1 as the coincidence detection point for each point to compare it with the present value. Reset the coincidence output signal or change the coincidence detection point with the sequence program. Controlling equipment according to the operating status, such as change of the coincidence detection point according to condition, is possible.

1 - 2

1.1 Features

OVERVIEW

(b) Continuous comparison function

(6) Mounting the coincidence output test function (when using the

continuous comparison function)

By using the coincidence output test function, wiring of the coincidence output terminals (EQU1, EQU2) and operations can be checked without count operation.

(7) Preset function

The present value when the preset command (Y04) is input or the preset input terminal (PRST) is turned ON can be overwritten to preset value.

Set from 1 to 16 as the coincidence detection point for each point to compare it with the present value (Only 1 point can be compared simultaneously). Whenever a coincidence is detected, the coincidence output signal is reset or the coincidence detection point is changed automatically. If this function is used when the coincidence detection point is predetermined, the sequence program can be reduced, which brings improvement in takt time.

CONFIGURATION

(8) Latch counter function

The present value when the latch counter execution command (Y07) is input or the latch counter input terminal (LATCH) is turned ON can be latched.

(9) Executing the preset function/latch counter function with external

control signal

Since the QD64D2 is independent of scan time of the programmable controller CPU, disparity in a span before executing the preset function/latch counter function can be lessen.

(10)Fuse blown at external output part is detectable.

The QD64D2 can detect fuse blown at external output part and notify it with the blown fuse detection flag (X1F) and LED display on it.

(11)Easy setting using GX Configurator-CT

The QD64D2 setting can be performed on screen by using GX Configurator-CT sold separately. Thus, the number of sequence programs results in decreasing and checking a setting status or operation status of modules easily.
