CAUITION
⑧ When the warning LED on the CONTROLLER blinks, conditions exist that could result in dangerous
operation. Check operating conditions and continue to use only after correcting the problem.
⑨ When using CONTROLLER continuously, refer to continuous area on torque Characteristics
Graph and check LOAD Monitor LED for a maximum output (3 Green Lamps).
⑩ Do not install the system next to RF noise sources, as malfunctions can occur.
⑪ If smoke, noise or strange odors eminate from the CONTROLLER or motor spindle, immediately
turn OFF the Main Power Switch.
⑫ Do not place anything on top of the CONTROLLER.
⑬ When installing the CONTROLLER, never place them in areas where vibration and shock are
present or possible. This may cause a malfunction to occur.
⑭ When using in a place where the power conditions are poor, take measures to enable a
supplied input power within the speci ed voltage uctuation.
⑮ Do not place the CONTROLLER near any source of heat. The temperature inside the
CONTROLLER will rise, resulting in a CONTROLLER failure.
⑯ Attach the provided Connector Cover for safety and dust proofing when not using Input /
Output Connecter A / B or Serial I / F Connector.
⑰ Do not press the switches on the operation panel of the CONTROLLER with a sharp-pointed tool.
⑱ Don't touch the heat sink of CONTROLLER. This may avoid burns to your skin.
⑲ When using SELECTOR with CONTROLLER, please use E3000 SELECTOR.
⑳ When disposal of a CONTROLLER is necessary, follow the instructions from your local
government agency and dispose as an industrial waste.
When using the Air Bearing Spindle, please supply the recommended regulated air pressure to
the Air Bearing. When rotating the spindle with less the regulated air pressure, this may make
you damage to the spindle or the CONTROLLER.
Be sure to clean the collet and collet nut, the inside of the spindle before replacing the tool. If
ground particles or metal chips stick to the inside of spindle or the collet, damage to the collet
or spindle can occur due to the loss of precision.
Always clean the tool shank and the machine spindle taper before installing the tool in the machine.
When sizing the correct collet size to the tool shank diameter, a tolerance of + 0 ∼ - 0.01mm is
strongly recommended. A tool shank within the + 0 ∼ - 0.1mm range is mountable, however,
this may cause poor concentricity and or insuf cient tool shank gripping force.
Select suitable products or tools for all applications. Do not exceed the capabilities of the
spindle or tools.
Do not stop the supplied cooling air to the motor, spindle, motor spindle, during operation of
the machine.
Removing the air pressure from the motor, spindle, motor spindle, causes a loss of purging,
allowing the motor, spindle, motor spindle, to ingest coolant and debris. This will cause
damage to the motor, spindle, motor spindle.
Carefully direct coolant spray to the tool. Do not spray directly on the spindle body. If large
amount splay directly on the spindle, it may cause excess load of the motor rotation with loss
of durability to the motor / spindle.
Stop working immediately when abnormal rotation or unusual vibration are observed.
Afterwards, please check the content of Section " 20. TROUBLESHOOTING ".
Always check if the tool, collet or collet nut are damaged before and after operating.
After installation, repair, initial operation, or long periods of non operation, please refer to
Operation Manual on the spindle / motor spindle detailed in " BREAK - IN PROCEDURE ". When
checking the spindle, no vibration or unusual sound should be observed during rotation.
