4.1 Module Installation

4.1.1 Instructions for handling

Use the Motion controller in an environment that meets the general specifications contained in this
manual. Using this Motion controller in an environment outside the range of the general specifications
could result in electric shock, fire, operation failure, and damage to or deterioration of the product.
When the modules are installed to the base unit while pressing the installation lever located at the
bottom of module, insert the module fixing projection into the fixing hole in the base unit until it stops.
Then, securely install the module with the fixing hole as a supporting point. Incorrect installation of the
module can cause an operation failure, damage or drop.
When using the Motion controller in the environment of much vibration, tighten the module with a
screw. Tighten the screw in the specified torque range. Under tightening may cause a drop, short
circuit or operation failure. Over tightening may cause a drop, short circuit or operation failure due to
damage to the screw or module.
Be sure to connect the extension cable to connectors of the base unit correctly. After connecting,
check them for looseness. Poor connections could cause an input or output failure.
Completely turn off the externally supplied power used in the system before installation or removing
the module. Not doing so could result in electric shock or damage to the product.
Do not install/remove the module onto/from base unit or terminal block more than 50 times, after the
first use of the product. Failure to do so may cause the module to malfunction due to poor contact of
Do not directly touch the module's conductive parts and electronic components. Doing so may cause
an operation failure or give damage to the module.
Lock the control panel and prevent access to those who are not certified to handle or install electric
Do not touch the heat radiating fins of controller or servo amplifier's, regenerative resistor and servo
motor, etc. while the power is ON and for a short time after the power is turned OFF. In this timing,
these parts become very hot and may lead to burns.
Remove the modules while paying attention.
