WARNING
⑩ When installing a tool, tighten the collet correctly and check again the collet and collet nut before
use. Do not over-tighten the collet. This may cause damage to the spindle.
⑪ Do not use bent, broken, chipped, out of round or sub-standard tools, as this may cause them
to shatter or explode. Tools with fractures or a bent shank will cause injury to the operator.
When using a new tool, rotate it in a low speed and increase speed gradually for safety.
⑫ Do not exceed the recommended maximum allowable speed of the tool. For your safety, use
speeds below the maximum allowable speed.
⑬ Do not apply excessive force. This may cause injury to the operator by slippage or damage of
the tool, or loss of concentricity and precision of the motor spindle.
⑭ When installing the motor spindle, make sure the Main Power Switch of the CONTROLLER
turned OFF before installing.
⑮ Whenever installing the motor spindle to a fixed metal base, ensure that the fixed metal base is
grounded in order to avoid the risk of an electric shock.
⑯ Do not use with held horizontally. This may cause malfunction and damage.
⑰ Use a power cable that satisfies the prescribed safety standards and local electrical codes for
your country. Also select the proper cable size considering the input voltage and current.
CAUTION
① A motor cooling and spindle purge air is required to operate the system correctly.
The input air line must be connected to the air inlet joint on the front of the CONTROLLER.
Air pressure between 0.25 - 0.3MPa (36.3 - 43.5psi) must be supplied.
② The motor spindle requires air for cooling and purging. Ensure that this air supply is clean and dry.
Introduction of dust, moisture and other contaminants into the CONTROLLER and motor spindle
will cause damage to the internal components.
③ If water or oil is allowed to enter the CONTROLLER, failure of the CONTROLLER may result.
④ Do not hit, drop or subject the motor spindle or CONTROLLER to any type of shock. This will cause
damage to internal components and result in a malfunction.
⑤ Do not disassemble, modify or attempt to repair the CONTROLLER or motor spindle. Additional
damage will occur to the internal components. Service must be performed by NSK NAKANISHI or
an authorized service center.
⑥ Never place the air vents upward or block the air vents of the CONTROLLER when installing the
CONTROLLER.
⑦ Motor will make a sudden stop when Error LED lights or error output signal is generated. Check and
correct the cause of the malfunction before continuing use. Failure to correct the problem will result
in damage to the CONTROLLER and motor spindle.
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 the CONTROLLER continuously, refer to continuous area on torque Characteristics
Graph and check the LOAD Monitor LED for a maximum output (3 Green Lamps).
⑩ Do not install the CONTROLLER next to RF noise sources, as malfunctions can occur.
⑪ If smoke, noise or strange odors emanate 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 specified voltage fluctuation.
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.
