CAUTION
⑰ Attach the provided connector cap for safety and dust proofing when not using the Motor
Connector No. 1 / No. 2.
⑱ Do not press the switches on the operation panel of the CONTROLLER with a sharp-pointed tool.
⑲ When disposal of a CONTROLLER is necessary, follow the instructions from your local government
agency and dispose as an industrial waste.
⑳ 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 the spindle or the collet, damage to the collet
or the spindle can occur due to the loss of precision.
㉑ Always clean the tool shank before installing the tool in the spindle.
㉒ 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 insufficient tool shank gripping force.
㉓ Select suitable products or tools for all applications. Do not exceed the capabilities of the motor
spindle or tools.
㉔ Do not stop the supplied cooling air to the motor spindle during operation of the machine.
Removing the air pressure from the motor spindle causes a loss of purging, allowing the motor
spindle to ingest coolant and debris. This will cause damage to the motor spindle.
㉕ Carefully direct coolant spray directly on the tool. Do not spray directly on the motor spindle and
collet nut. Large amounts of coolant sprayed directly on the motor spindle and collet nut may cause
excess load of the motor spindle causing a loss of durability and longevity of the motor spindle.
㉖ Stop working immediately when abnormal rotation or unusual vibrations are observed. Immediately,
please check the content of section P111 " 20. TROUBLESHOOTING ".
㉗ Always check if the tool, collet, collet nut, connection hose and supply air hose for damage before
and after operating.
㉘ If the collet or collet nut show signs of wear or damage, replace them before a malfunction or
additional damage occurs.
㉙ After installation, repair, initial operation, or long periods of non operation, please refer to Operation
Manual on the motor spindle detailed in " BREAK - IN PROCEDURE ". When checking the motor
spindle, no vibration or unusual sound should be observed during rotation.
㉚ Secure the power cord by use of the power cord hook after connecting the power cord to the Main
Power Inlet with Power Supply Fuses.
㉛ Setting parameters allows the motor to run without motor cooling. When using, be aware of the
possibility of overheating.
㉜ Be sure to attach the Brackets to the CONTROLLER when there is a possibility of the CONTROLLER
to fall.
㉝ Confirm the maximum speed of the motor spindle in the operation manual supplied with it before
setting its speed on the CONTROLLER. Excessive speed may cause damage to the motor spindle,
and this may also cause the motor spindle to overheat and shorten its service life.
㉞ When using this CONTROLLER for mass production, please consider the purchase of an additional
CONTROLLER to be used as a back-up in case of emergency.
㉟ Securely connect the compressor supply connection hose to the Air Line Kit, and connect the air
hose to the Air Line Kit, the CONTROLLER and the motor spindle to avoid accidental disconnection
during use.
㊱ Disconnect CONTROLLER from power before doing maintenance on replacing tools or fuses as
specified.
㊲ Do not use in flammable or explosive atmospheres.
㊳ Send back to NSK NAKANISHI or an authorized service center for servicing / repair.
㊴ Use the CONTROLLER in pollution degree 2 environment.
