[Design Precautions]
● Do not write any data to the "system area" of the buffer memory in the intelligent function module.
Also, do not use any "use prohibited" signals as an output signal from the CPU module to the
intelligent function module.
Doing so may cause malfunction of the programmable controller system.
● An absolute position restoration by the positioning function may turn off the servo-on signal (servo off)
for approximately 60ms + scan time, 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]
● 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.
[Installation Precautions]
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
● Use the programmable controller in an environment that meets the general specifications in the Safety
Guidelines provided with the CPU module or head module. Failure to do so may result in electric
shock, fire, malfunction, or damage to or deterioration of the product.
● To interconnect modules, engage the respective connectors and securely lock the module joint levers
until they click. Incorrect interconnection may cause malfunction, failure, or drop of the module.
[Wiring Precautions]
● Check the terminal layout before wiring to the module, and connect the cables correctly.
