1Cautions for handling and operation
■Read these cautions carefully and only use in the manner intended.
■Safety instructions are intended to avoid potential hazards that could result in personal injury or
damage to the system. Safety instructions are classified as follows in accordance with the
seriousness of the risk.
①The ASTRO-E400Z/500Z/800Z is not a hand tool. It is designed to be installed on a NC
lathe or a special purpose machine.
②DO NOT connect or disconnect the electric cord or operate ASTRO-E400Z/500Z/800Z
with wet hands. Failure to follow this warning may result in electric shock.
③Protect ASTRO-E400Z/500Z/800Z control unit from coolants and moisture contamination.
Failure to protect the control unit can result in damage to internal components and short-
circuits within the ASTRO-E400Z/500Z/800Z control unit and possible injury to the
operator or other personnel.
④Always use a protective cover around the spindle, wear safety glasses, dust mask,
hearing protection and gloves while the motor is running.
⑤Never touch the motor, spindle or cutting tools while the system is operating.
⑥Use only the proper input power source voltage and check the voltage setting on the
ASTRO-E400Z/500Z/800Z control unit to prevent damage to the control unit or injury to
the operator.
Thank you for purchasing the Ultra-Precision, High-Speed spindle system, ASTRO-E
400Z/500Z/800Z. ASTRO-E400Z/500Z/800Z System is designed for use on CNC lathes,
robots, NC lathes and special purpose machines. The motor, spindle and control unit are
designed to work as an integrated system capable of 0-40,000min-1(400Z) ,0-50,000
min-1(500Z),0-80,000min-1(800Z). This system utilizes air to cool the motor and protect the
spindle from contaminants, please use an airline kit to ensure that clean, dry, properly
regulated air is supplied to the motor and spindle. Please read this Operation Manual
carefully prior to use.

A hazard that could result in bodily injury or damage to the system if the
safety instructions are not followed
A hazard that could result in light to moderate bodily injury or damage to the
system if the safety instructions are not followed.

①DO NOT block the cooling vent on the back of ASTRO-E400Z/500Z/800Z control unit.
Blocking the air vents will greatly increase heat buildup in the control unit and cause
damage to the internal components of the control unit.
②When using tools at motor speeds of less than 2,000min-1(rpm), the appropriate speed
reducer(For ASTRO-E400Z/500Z)needs to be attached.
③Please check to ensure that the average spindle load does not exceed the continuous use
area of the load meter. Check the (Load Monitor) and make sure that no more than the 3
green LED,s are lit.
④Only use tools at less than the maximum speed recommended by the tool manufacturer.
( Use of tools in excess of the manufacturer,s maximum allowable speed can cause
damage to the motor, spindle and machine tool and possible operator injury.)
⑤Always clean the tool shank and the chuck prior to use. If ground particles or metal chips
are stuck inside thespindle or chuck, this will cause damage to the chuck and/or spindle
and loss of precision.
⑥Do not install the ASTRO-E400Z/500Z/800Z near RF noise sources this can cause
malfunction or damage.
⑦When error lamp flashes or errors occur, the motor will stop. Before restarting the system
or continuing operation, check and correct the cause of the malfunction. Failure to correct
the problem will result in damage to the control unit, motor and spindle.
⑧Always check the cause of a warning when Warning Lamp flashes or Warning output
signal is detected.
⑨DO NOT drop or hit the control unit, the motor and/or spindle. This will cause damage to
the internal components and result in reduced performance, precision and possible
system failure.
⑩Clean dry air is required for cooling the motor and preventing contaminants from entering
the motor and/or spindle. If dust or water enters the motor and/or spindle, it will result in
damage to the motor and spindle.
⑪Make sure that the collet chuck is firmly tightened prior to rotating the spindle.
⑫The motor can be rotated at 500min-1 for centering. Do not attempt to use 500min-1 for
machining.
⑬Do not disassemble or attempt to repair the motor, spindle or control unit. There are no
user servicable parts in the system.
⑭Do not place anything on ASTRO-E400Z/500Z/800Z control unit. This will cause damage to
the control unit.
⑮If smoke, noise or strange odors are emitted from the control unit or motors, immediately
turn off the power switch.
⑯The connector cap needs to be installed on CN1/CN2, when AUTO control mode is not
used or if CN1/CN2 are not being utilized.

① A high-speed brushless motor is used to achieve extremely high speed and eliminate the nuisance of
brush maintenance.
② Motor speed is digitally displayed.
③ Wide motor speed range: 0-40,000min- (400Z ) ,0-50,000min- (500Z ) and 0-80,000min- (800Z).
Cutting speed range is: 2,000-40,000min- (400Z) 2,000-50,000min- (500Z) and 20,000-
80,000min- (800Z). The motor can also be set for 500 min- rotation for centering.
④ Automatic control and monitoring of spindle functions are possible.
⑤ The motor/spindle housing is made of Stainless Steel (SUS-4 6) precision ground to ¯30mm OD.
The motor/spindle is very easy to mount on NC lathes or special purpose machines.
⑥ A wide variety of spindles and speed reducers are available making this system highly flexible.
⑦ Wide range of collet chucks is available.
⑧ The front panel of the ASTRO-E400Z/500Z/ 800Z control unit can be detached and the cord can be
extended to Max.4m with  the control panel extension cord  (option). This cord allows the control
unit,s front panel to be remotely mounted in a convenient location.
⑨ A safety relay is installed to conform to European safety standards.
The  a  contact is used for the electric line and the  b  contact output makes detection of an open
motor electric line circuit possible. This system can be integrated with the machine,s safety systems
to help enhance safe, automatic operation.
⑩ The Emergency Stop Signal can be used to operate the safety relay automatically. When the
Emergency Stop Signal circuit is open the power lines between the control unit and the electric motor
are disconnected.
⑪ ASTRO-E400Z/500Z/800Z is capable of being connected to 5V to 230V power sources. The
control unit incorporates a voltage selection switch; this switch is set to the proper position for the
voltage being used.
