(6) Usage
CAUTION
Use C80 in an environment that meets the general specifications contained in this manual. Using C80 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 mounting the module, be sure to insert the module fixing hook on the module's bottom into the
module fixing hole on the base unit. Incorrect mounting could cause an operation failure or a damage/drop
of the unit.
Hold down the module loading lever at the module bottom and securely insert the fixing hook into the fixing
hole in the base unit. Install the module with the module fixing hole as a supporting point. Incorrect
mounting could cause an operation failure or a damage/drop of the unit.
Be sure to fix all the modules with screws to prevent them from dropping. The fixing screws (M3 x 12) are
to be prepared by user.
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 install the extension cable to connectors of the basic base unit correctly. After installation,
check them for looseness. Poor connections could cause an input or output failure.
Completely turn off all lines of external power supply used in the system before loading or unloading the
module. Not doing so could result in electric shock or damage to the product.
Do not mount/dismount the modules or base over 50 times. Mounting/dismounting over 50 times may
cause an operation failure.
Do not directly touch the module's conductive parts or electronic parts. Touching these parts could cause
an operation failure or give damage to the module.
Do not touch the radiating fin of the CNC CPU module while an electric current is supplied or in a short
while after the power OFF. Touching the fin may cause burns. Take care when removing the unit.
The metal part becomes the high temperature.
When removing the unit, always remove the fixing screws and then take the fixing hook out from the fixing
hole. Incorrect removal will damage the module fixing hook.
When the module fixing screws are used, remove the screws first and module from the base unit. Failure
to do so may damage the module.
The module surface temperature may be high immediately after power-off. When the module is removed,
pay attention to the burn injury.
Install an external emergency stop circuit so that the operation can be stopped and the power turns OFF
immediately when unforeseen situation occurs. A contactor, etc., is required in addition to the shutoff
function mounted in the controller.
Turn OFF the power immediately if any smoke, abnormal noise or odor is generated from the controller,
drive unit or motor.
