Q/L series module AnS/A series module

WARNING

● Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable controller.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting

operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.

(2) Machine OPR (Original Point Return) of the positioning function is controlled by two kinds of data:

an OPR direction and an OPR speed. Deceleration starts when the near-point watchdog signal
turns on. If an incorrect OPR direction is set, motion control may continue without deceleration. To
prevent machine damage caused by this, configure an interlock circuit external to the
programmable controller.

(3) When the CPU module detects an error during control by the positioning function, the motion slows

down and stops.

(4) The programmable controller stops its operation upon detection of the following status, and the

output status of the system will be as shown below.

Also, all outputs may be turned on if an error occurs in a part, such as an I/O control part, where
the programmable controller CPU cannot detect any error. To ensure safety operation in such a
case, provide a safety mechanism or a fail-safe circuit external to the programmable controller.
For a fail-safe circuit example, refer to the User's Manual (Hardware Design, Maintenance and
Inspection) for the CPU module used.

(5) Outputs may remain on or off due to a failure of a component such as a transistor in an output

circuit. Configure an external circuit for monitoring output signals that could cause a serious
accident.

● In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.

● Configure a circuit so that the programmable controller is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect output
or malfunction.

● Configure a circuit so that the external power supply is turned off first and then the programmable
controller. If the programmable controller is turned off first, an accident may occur due to an incorrect
output or malfunction.

● For the operating status of each station after a communication failure, refer to relevant manuals for
each network. Incorrect output or malfunction due to a communication failure may result in an
accident.

2

WARNING

● When changing data from a peripheral device connected to the CPU module during operation,
configure an interlock circuit in the program to ensure that the entire system will always operate safely.
For other controls to a running programmable controller (such as program modification or operating
status change), read relevant manuals carefully and ensure the safety before the operation.
Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure. To prevent this, configure an interlock circuit in the program, and determine
corrective actions to be taken between the external device and CPU module in case of a
communication failure.

● An absolute position restoration by the positioning function may turn off the servo-on signal (servo off)
for approximately 20ms, and the motor may run unexpectedly. If this causes a problem, provide an
electromagnetic brake to lock the motor during absolute position restoration.

[Design Precautions]

CAUTION

● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.

● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.

● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size. Design circuits so
that the entire system will always operate safely, regardless of the time.

(2) Control data can be logged without missing a change (continuous logging).

Data logging is available every scan or on the millisecond time scale. Since changes in the specified control data
can be logged, the data logging function is effective to identify the cause of a problem. Also, logging is performed
at a high speed so that equipment can be analyzed with high accuracy.

Data logging is the best-effort type*1 function. Logging may not be performed at a specified sampling interval because
processing time may vary depending on the configuration or the other connected devices. After configuring the system,
thoroughly examine the processing time before starting the system operation. ( Page 161, CHAPTER 10)

*1 The concept of obtaining the maximum performance from the condition at the time.

(3) Problem analysis can be speeded up. (Trigger logging)

The states and changes in data can be stored as the data before and after a trigger. Since only the data before
and after occurrence of each problem can be stored, the cause of the problem can be identified quickly, and file
space can be saved.

logging).

Using the specification period logging (Page 61, Section 6.3.3), data can be collected only while the specific
conditions are met, and files can be saved for each specified period.
Capacity increase resulting from collecting unnecessary data can thus be prevented, and time taken to analyze
and organize data can also be shortened. Even when the conditions change, all data that meet the changed
conditions can be collected.
Furthermore, together with the data logging file name addition instruction (SP.LOGFILES) (Page 175,
Section 11.3), the specification period logging allows any character to be added to the data logging results for
each specified period, facilitating the control of data logging files.

The specification period logging is available only for the High-speed Universal model QCPU and the Universal model
Process CPU. Before using the specification period logging, check the versions of the CPU module and configuration tool
used. ( Page 190, Appendix 2)

(6) A large volume of logging files can be stored.

Use of an SD memory card of up to 16GB enables a long-term logging.

(7) Data sampling for troubleshooting can be instructed easily.

Data required for troubleshooting can be collected by simply sending an SD memory card (where auto logging
setting data are stored) to the factory floor and inserting it into the slot of the CPU module. (Auto logging function)
Furthermore, the logged data can be analyzed if the SD memory card is returned to the office after termination of
the logging.

(8) Data logging files can be transferred from the CPU module to the FTP server

By using the data logging file transfer function, the CPU module serves as an FTP client, and data logging files in
SD memory cards can be transferred to the FTP server. ( Page 82, Section 7.4) Since data logging files can
be managed by one FTP server, data management and maintenance work can be reduced.
